The Ospho needs to be neutralized before applying epoxy over it. If the ospho has dried, re-wet with ospho, then rinse with water and dry thoroughly. The epoxy will adhere to the ospho, not the base metal, if it is not neutralized, and could lift if the ospho lets go.
@@DAT240Z72 Completely wrong. Test? I have personally seen numerous instances of adhesion failures on finished paint jobs that didn't neutralize the acid and remove residue. The instructions of the acids that say neutralization is not required or that don't instruct how to neutralize are misleading.
@DAT240Z72 you are supposed to rinse the acid off. It doesn't matter what product you use, it's all phosphoric acid and needs to be neutralized before painting. After you rinse the acid off, scuff with scotch Brite or 320 grit paper, wax and grease remover, prime and paint.
I have used ospho for 20t years . Had a old car in the barn for about 20 yrs never rusted ! Started using it on farm equipment then on anything that may rust. Love the stuff
Great!. I've been using Ospho on a 83 Cub Cadet restore. The locals here in rural southern Georgia highly recommended it. Also on an old Sears and Roebuck garden trailer that amazingly hardly has any rust and built like a tank. Subscribed and enjoyed your video. Can never have enough projects going. Life is good
Same thing in Cleveland Ohio's winters but more like 2 winters. We use so much road salt that the DOT usually runs out and gets extra from PA. I think Maine being a liberal democratic state they don't even use road salt but sand mixed with the tears of Bernie Sanders ad Steven King to melt the snow instead...LoL
I do professional powder coating and phosphorous is a staple to prep metal. Lowes and home depot sell it as metal prep or concrete etch. It does not need anything done after dry time except wiped down for paint. The acid etches into metal for immediate adhesion for paint. If doing bare metal for regular paint then use a zinc added primer to keep rust growth. No neutralizing is neccessary before paint and must be dry. We do lots of ceracote and prizma powder coating. Ceracote even has a brush on application that doesn't need oven baked either! Nice video and I miss Kentucky being born there and live in ohio now. Still watch the Wildcats though!!!
Datsuns! Why did they ever think to get rid of these & that name! Fun cars & trucks :D. Great vlog again, I absolutely love your videos! thank you for taking the time!
Thanks for watching! I love Datsuns, I am excited to get this one back on the road. But like I said before, it needs a lot of work gonna be a marathon.
The reason why you don't use epoxy and you use an oil base, it's because of the pH of the product. Epoxy encapsulates, whatever is there. So if you don't neutralize it prior to putting the epoxy on, you just f***** your metal. There will still be enough oxygen for the chemical reaction to take place. With the metal being a higher pH any rock chip, scratch, gap, holiday... It's going to just start eating that s*** away. There are tons of videos showing this as an experiment for paint finishes without neutralizing. You can see something's wrong with the one year mark. By the time that the 5-year was finished so was the steel.
If you are not going to bare steel, remove the ospho coat with Hirsch miracle paint then paint. It won’t come off. If you go to bare metal coat with ospho to etch the metal remove, then coat with acid based self etch primer and paint.
I'm afraid moisturizer would get behind the paint, and it would rust, I would have no way of cleaning it up to repaint if I had to. That Ospho seems to really do a good job sealing the metal, and I don't believe it would ever peel. I may recoat with that if I have to.
Did you buy acid on line or local? When you painted frame, did you blow paint up inside, have a rusty frame for a Lemans that I need to do . This looks like a good way to go . Glad you're back...
Thanks! I bought through Amazon. I only sprayed Ospho inside the frame and blew it out with air after about 1 hour. I recommend not letting it puddle or drip. I also recommend letting the Ospho sit until it's complete cured then coat with oil based paint so you can skip the last 80 grit sanding I did.
Thanks! I'm eager to get the Datsun on the road, but takes time and money. Just got a part from your neck of the woods from Danst Performance for the Prelude.
I used Ospho on a car I am restoring and it created a mess for me to clean up. It dried to a white powder.and created more rust. Can anyone tell me why?
Love your no nonsense videos. Glad to share!

No it doesn’t. Test first.
The acid is only active when it’s wet.

@@LR6092actually you don’t wipe this off let dry spray right over it

I also got bubbling and hardening because I sprayed on the ospho. I started with a brush, and that part is much smoother. Lesson learned.

First person I actually seen pay attention to the inside of the frame 💪🏽💪🏽💪🏽👍🏾👍🏾♻️
Really like the method for spraying inside the chassis 👍
Another good video benny
Thank you! It worked out good I thought, what I didn't show was blowing the excess out of the frame after about 1 hour.
Here in Maine, that frame isn't rusty at all, just a little surface oxidation. Buy a new truck here and your frame will look like that in 3 years.

VERY NICE WORK ON THE RUST specially in the inside whit the phosphoric acid

Nice 520... had a PL521 and couple 510's and roadsters back in the day. Dad had a 520. Friend has a sss 311 wagon. Miss those years.
@@coachgeoThanks! You guys had all the good ones!
Turned out excellent!

I used 30% vinegar recently to remove rust it was fantastic and fast
@@airecraft1 Thanks for subscribing !
Would you think there's a benefit to spray an oil based paint inside the frame with that 360 spray head?
I'm afraid moisturizer would get behind the paint, and it would rust, I would have no way of cleaning it up to repaint if I had to. That Ospho seems to really do a good job sealing the metal, and I don't believe it would ever peel. I may recoat with that if I have to.
urethane doesn't stand up to UV either unless it's aliphatic based
That internal frame sprayer is way cool
Thank you! It did the job very well.
This was awesome, thanks for sharing.
Here's a comment for your comments ❤I love Datsun I'm not sure about Nissan 😮
Awesome work ❤
@@mopardave500 Thank You!
Frame looks dope!!
Thank you!
Enjoyed the video and the explanation. Looking forward to the lift refresh, the Prelude project and the Datsun Truck of course. Thanks Ben! 👍🏻
Thanks! We have a lot to do the next couple weeks!
What brand is the scaling hammer are you using?
Unitec, I could not be happier with it very good quality tool.
Great video Benny. Are you planning to re-chrome those bumper and other parts that were once shinny?
Thank you! The Benny can't afford chrome unfortunately. White or silver paint will have to do the job.
This stuff works great i use it for a lot of projects i do
Looking good, you have the same spray booth I do! :D
Thanks! Those are the cheapest booths available. 😂😂
Baking soda spray on coating of that will neutralize it for sure.
Why are you worried about instructions when you don't follow them?
Nice. I find these sorts of videos instructional.
Thanks Bob!
Looks Great!...
Urethane paint is ok, but it will typically peel off far quicker as it's a lower quality of paint...

Love those old mini trucks. Great job
Thank you! I like em too, the older the better for me.
It's like using it to fix other fiberglass body work with to.
Great ole truck!
Glad to see the Datsun again greets from England
Thanks! I'm eager to get the Datsun on the road, but takes time and money. Just got a part from your neck of the woods from Danst Performance for the Prelude.
I'm at a loss of words... Datsun??? What ever your doing is?? Goog luck
Tell me the brand gun that is I cannot find one online that works for nothing
I don't know what kind it is. I'll see if I can find a name in it.
Hi Benny? Do you still have your Z900RS?
No, had to sell it to fund other projects. I have a klx300sm right now.
Sorry to hear that. I sold my Z1900 for the same reason😢. While I have your attention, is the Ospho expensive?
@1buckola That's ok something else will come up. When it's the right time.
looks good
@@jebert327 Thanks!
*_I never follow the Destructions ..._*
Gonna try this on the under carriage of my truck 🛻
I used Ospho on a car I am restoring and it created a mess for me to clean up. It dried to a white powder.and created more rust. Can anyone tell me why?
@user-tn1hk6zm2freedom Sometimes it works well , and other times, it does that. Maybe you put it on, too thick ? Idk
@@kentuckyyankee I don't understand it creating more rust.
Paint will not stick to it.
When it comes to paint. Why wouldn't you follow the instructions if you wanted it to last?
Bs job first sand blast then clean and then inching primer and then good quality under coating that’s it
@@buenaventuramarte5572 Where do you get inching primer? I've never heard of it?
Put your grpund clamp away from your work area not nessacary to have it that cl9se to welding area
🤙
Heat
I need a tractor
They sure do help, I like the little compacts.
Ospho is crap.
