Wonderfully done video, I like how straight forward it is and give you all the details you need to paint your pc's aluminum areas!
Clear, simple and well presented. Great video!
Thanks! This vid was very helpful. I'm work on a big sheet metal project. I just taught my self how to properly paint metals. Thank you once a gain.
.
Definitely doing this for my bicycle project! The copper color came out just the way Im wanting it. Thanks for the video!

Those look really good
Thanks, I Will try paint an old cassette player Panasonic RQ-SX41 (blue) case. I'm restoring it. Your video and tips just fit on my intentions. Now I need to figure out how reapply the withe letters after finish the paint.
Thank you for explaining it so clearly
You're wel;come, I love doing DIY paint guides, I have many more here, ua-cam.com/play/PLtGuyF7aQwsvjQg-6hhDwCamR2rXUzxZ0.html
After a partially failed aluminum anodize and dye, this is my next option without having to buy new parts. Thanks for providing the exact info I was looking for. :)
awesome, the key element is the SEM Self Etching Primer, just be sure to apply outside or in really well ventilated area, as it's very TOXIC.
Does it have to be the SEM brand, or will any self etching primer do? Thanks again for all the great info.
I can't vouch for other products, sorry.
Bill Owen Can i use the cheaper mask?
Excellent video, thank you for sharing.
Thank you too!
Another awesome vid Bill, have you ever consider doing a video about powder coating small part like compression fitting for copper tubing ?
I search all over youtube but haven't see anybody do a video about that.
exactly what i was looking for thank ytou!!
Hello sir. What should I use for painting an old graphite tennis racket. What are your suggestions?
That PC case foot is machined, right? Will that same painting process also work on die cast aluminum parts? And will they look as nice? Thanks!
Super helpful, thank you!!
Can I use this process to paint aluminum that has been anodized?
would this primer hold up by itself without paint? thanks
Does this leave a tacky paint finish when you handle it? Like does it still feel like aluminum or aluminum that has a coat of paint over it.
I have an aluminium alloy ipad case...can I follow the same process as this?
I'm curious as to how much the dimensions are changed after applying 4 coats each of primer, paint and clear coat. Hopefully its less than 1/2 mm.
Great job.
Can i paint my mobile aluminium body and make it look like new ?
How did the paint hold on to the aluminum?
Hi. My name is Jeff. I have a professional vintage cassette recorder Tascam 122MKIII that has a front panel that is anodized aluminum and has some damage. I can send pics. Are you able to repair this? Thank you
Can I paint over anodized Aluminum?
Heelp 🙏🙏🙏
Old lady here. Does anyone know if this can be done with a liquid solution using a sponge applicator?
We want to repaint our anodyzed aluminum windows which are all weathered and had the paint falling of in sections.
Much appreciated.
Clear can be shot while paint is wet. I have done so numerous times and works good. My theory is that clear clings to wet paint.
Love the guide

Did you sand before clear coat?
Thanks for this.
150 grit seems a bit aggressive. Leaves gouges. A 320 sanding sponge seems to work better for me.
Not really a problem if you're applying 12 coats of paint.
The 4 coats of primer alone will fill in the scratches.
@@ChristopherJones16 It just means more work....and more material. So, why??
@@TangoCharlieAlpha me personally would use 320 but if all I had was 150 I wouldn’t worry too much about the scratches showing with 4 coats of primer and 4 coats of paint. I think 320 is what most painters use when they paint aluminum. Probably not extra work for someone though if they just use 150 and nothing else. His legs seem to have came out fine using it. Then again perhaps that’s why he needed 4 coats of primer. I’m not painter. I usually stick with two coats of primer. For most things I paint. Sometimes just one coat depending on the object. If that’s the case then yeah 150 will need to be followed up with less coarse sandpaper. To each their own.
they look sick pretty cool guys
Thanks for watching, Any new builds in the works Tek?
+Bill Owen im working on something just saving up some money for all the parts.
thanks, great tutorial. to the point
Thanks for watching Bill at mnpctech.com
Hey quick question... great video first off... i am going to be painting some brushed aluminum paddle shifters for my Camaro; are the scratches from sanding visible once painted? That is my biggest concern at the moment. Reason i ask is because i noticed you used some pretty rough sandpaper. Any help is greatly appreciated and thank you in advanced!
You can see the final finish in the video. If youre concerned this isnt going to meet your expectation, I suggest taking your parts to local Powdercoating Shop, so your parts have a thick and durable finish to last for the life of your Camaro. Have a good one, Miguel!
I’d go with a 400, then step it up to 600 and then 800. Rostoleum makes a variety pack of automotive sandpaper you can find in Walmart that has all the grits you’ll need for like $4. If you still see some after the etching primer, hit it with a coat of regular primer or “high build”. But that’ll likely be unnecessary.
I’m always a fan of just the 800, but put the object (assuming it’s xirculr and symmetrical) in a drill and spin the hell out of it. Sand it that way.
Awesome
I'm looking to protect bare aluminum on running boards I just purchased on the underside of them to protect them I guess I just follow the same procedure that you did for the video? I live in an area where it snows a lot and I want to try to make them last longer the company I bought them from says they don't have issues with corrosion but I feel as though if I primer and paint them it would be much better protection then just the bare aluminum that is currently on them on the underside any kind of help or advice you could give me would be greatly appreciated thank you
Have them powder coated. They can do whatever color or clear coat finish you want. Powder coating offers the best durable coating.
I would like to paint a brown color of **flat/matte** sheen on top of this self etching primer. I think Rust-oleum only sells glossy sheens. Are there any recommendations what product to use? Can I use any paint? It would be for outdoor use. Thanks!
Rust-oleum does offer MATTE CLEAR finish too, www.rustoleum.com/pages/find-a-product/
Does this add any thickness to the object? I would like to do this to an outer barrel for my airsoft gun but Im worried about running into fitment issues when it cycles. Thanks for your help!
Yes, coating will add 1 to 2mm thick layer
I did something similar. Durability wasn’t up to par, and I’d powdercoat it if I did it again. In any case, I dusted the barrel while assembled with a light color. Let it dry. Then disassembled and masked off the areas where contact would be made with other parts. Simple as that
if i want to paint aluminium to matte black, can i only use the black primer?
No, you don't have to use Black primer.
Will the self etching primer chip a body filler directly attached to the bare aluminum? Thankyou
may chip, depending if the area will flex.
But will it void the warranty? :-P LOL!
You have a good one Mr (Overkill) Bill Owen
Kev B :-)
I did a test on an aluminum pop can with 2 coats of Rustoleum Self Etching Primer and 2 coats of Rustoleum Semi-gloss black and then 2 coats of Semigloss clear. I didn’t sand though before priming. Later that night I did a scratch test with my fingernail. It scratched off to bare metal easily. I let it sit over night and tried another scratch test mid day. Still coming off although a little less easily. This is disheartening. The nature of the piece I need to actually paint has hundreds of ridges on it that would take me a week to sand.
I'm painting my cast iron lathe. I used Rustoleum self etching primer. Do I need a coat of regular primer before my color coat?
no, youre fine.
@@Mnpctech_Giveaway_PC_Mods Thanks you. I put 3 coats of the self etching primer on and bought Sherwin Williams automotive grade single stage paint is what they're calling it.
(yes) That's what some people do in order to create a layer between the SEM and color coat because the Self Etching Primer is acidic.
Bill - Great video. It looks like the etching primer turned the pieces black. If you wanted them to be black could you skip the painting?
Yes, you could do just the primer if you like the look.
Is there a way to keep a nice silver finish with out anodising?
I'm doing something decorative that wont get much abuse.
apply enamel clear coat.
@@Mnpctech_Giveaway_PC_ModsThanks. What prep would you recommend?
You said 120 grit, then 150 grit. Does it make a difference?
I know this is a late reply, but no, it doesn't make a difference because there isn't much of a variation between the two grits. If he had said 120 and then 400, then that would make a pretty significant difference.
Do you not need to put a regular primer over the self etching primer?
No, just Self Etching primer, before paint, as stated in the video.
This is amazing and beautiful super well explained, would it also work for anodized aluminum?
Yes, absolutely
@@Mnpctech_Giveaway_PC_Mods thanks!
Im wanting to paint my bathroom trim. Will this self etching paint hold up to normal use since its bath trim? Can i use the etch paint outside with just a normal respirator mask....the cheaper ones? I hear Rustoleum makes a self etching paint.
Cheap mask should be OK, as long as you're in well ventilated area. May I ask, Trim for what exactly? If it's something that's going to get wet or collect condensation on the surface, the top coat of paint will eventually chip and peel off over time. This is why retail bathroom fixture and plumbing manufacturers finish their products with a plated surfaces or powder coating.
The shower and bathroom trim, but im not sure how it will hold up. Powder coating? Hmmm, wished there was a way to do it myself. 😕
My advice, take the pieces to local Powder coating outfit if you want a specific color, you can find Powdercoating Services under "Metal Finishing" in your local phone business listings or even check Google.
What if I want to spray paint it white
USE GREY PRIMER instead of BLACK in the video, Thank you, Bill at www.mnpctech.com
Does this effect the texture of the aluminum?
Yes, it's paint.
Hi Bill, wonder if you can help me. I'm getting flat faced machined 6063 parts with a high gloss machined finish - I would like to achieve consistent satin/matte (or the finish you have on your part). I need to do a little deburring on occasion but the toolpaths are so tight that the finish looks great but much too gloss. I tried spraying a matte clear laquer then gloss, then matte but found out the hard way that you need to unlock/rough the surface to allow bonding etc. Is your 6061 finished piece anodised? looks like it's been sanded with about 400-600 grit but its hard to tell from my novice eyes. I'm at the point now where I think I'm going to try some ultra fine scotchbrite pads etc. but any cheap tips would be great, I don't really want to add vapourblasting costs on top at this stage till I sell a few lol
In otherwords - how did you get you 6061 finish?
Our parts are made from 6061 aluminum and deburred with Medium Red Scotchbrite pads. Thanks for watching, Bill at www.mnpctech.com
Thanks Bill, appreciate it
Should I repeat the same steps for an aluminum dashboard ? 🤔🤔
Yes, you can use these steps and products for any bare aluminum surface.
Bill Owen thank you 😃🙏
I'm going to try this method on my aluminum paintball barrel. My paintball barrel is black and I want to go white or silver, does it matter what color primer I use?
Buy SEM Grey Primer, for Silver top coat, dont forget filtered mask and paint it outside, www.amazon.com/SEM-39683-Grey-Etching-Primer/dp/B000GTIRAU
Figured I had to use grey. Thanks for the quick reply and safety tips!
I got an aluminum bat that i want to paint gold... I' ll not really use it but keep it mainly for decoration... I already bought the Rust-Oleum metallic... Do i need to apply primer?
For decoration only, you don't need to apply the primer.
@@Mnpctech_Giveaway_PC_ModsOkay, thanks man
At 1.47 you're touching them. That's a "NoNo". Maybe put on the clean latex gloves before touching them or better still, don't touch them at all.
Did you let the copper paint cure for 24 hours before you put the clear coat on?
Yes, Thanks Scott
***** Ok, thanks. I wasn't clear on that when watching it. Planning on painting again and wanna make sure I do it right lol.
Perhaps use a 400 or ? grit pad rather than paper.
sure!@ Thanks for watching, Bill at mnpctech.com/
How durable is this coating? Would this process work for knife scales without chipping in just a shirt time?
it's paint, all paint will chip.
wb real anodizing?
Yes, if you have the resources, anodizing is great. Any new projects or builds in the works Punisher?
grande bill
150? Or 120? Sandpaper. I'm sure you said two different figures
either grit will work fine, Thanks for watching!
i thought that was a cone piece
looked better black.
use yellow primer
Thank you, what are you working on these days r2stik?
My science teacher is the creator of how to paint aluminum and he gets a lot of money
That's awesome, please have him watch my video and share any advice. Thank you
Those feet still holding up after 6 years? I guess the hardware is probably outdated by now
I definitely haven't used self etching primer in my closed garage without a respirator. I definitely didn't do that.
Agreed, it's pretty toxic. Just imagine microscopic barnacles attaching to your lungs. Any new builds in the works Overt?
I did do that. No builds but what I do need to do is mod a way to close off the top of an old corsair c70 case. Because of the way the top is designed there's no real way to get positive pressure going and it fills up with dust.Probably just going to bolt a painted sheet of steel to it.
If you want more positive pressure, how about a couple 140mm fans as intakes on top, with mesh screen filters? You can get c70 top filters here, www.demcifilter.com/c31/VENGEANCE-C70.aspx
Well I've got 140's laying about, I've used the demci filters before but I've never been a fan of the aesthetics. I might do that until I've got the time to do some cutting and painting. It's not as much fun if you buy the solution off the shelf. I actually used your guide to fix the window on the C70. Worked a treat.
You could get window screen from home improvement store and make your own grill for the top, maybe paint it a nice accent color
Americans are obsessed with feet :D
too many steps and too costly but result is neat.
Awesome
