If you see back ionization when shooting you can just toss it in the oven right before flow out maybe a minute or 2 and just lay a nice mist from far away over the whole piece and the powder will melt back together like it never happened.
Hello. I'm fairly new to powder coating. Your vids have been very helpful. I'm using the Eastwood gun (since starting out). So this is due to a bad ground. I've seen similar on a clear coat. For a second coat, do you have to get your ground down to base metal which would involve a scratch?? Also, would you do this same procedure if you have a clear coat that went bad - sand it, add another layer of color, and then re-clear coat it?
What do you warm the part up to before you spray it again. Also do you let it run the full cure time on the second try can the original coat over cure ?
I just did a part super chrome ll the second coat black chrome it fisheyed on me so I sanded out the fish eyes scuffed up the whole piece at 120 and recoated the whole piece flat black because I didn’t like the color it came out like bed liner... any tips on why?? Now I have to strip the whole piece and do it over..
You need to apply the redo coat just as heavy as the first coat. A sand paper finish is from putting too light of a coat on. Also be careful with 120 grit. It can make deep scratches
Back Ionization can occur for a few reasons, 1) You are recoating over existing cured powder coat. (2) You have applied too much powder on the first coat pass. (3) Poor earth. Remedies (1 & 2) Reduce micro amps on your powder coat controller, this this is called current limiting. (3) Clean all your contact points so earth is
I know it's frowned a pon But .😇on powders that tend to do that hot flocking at about 140 degrees will usually fix that issue so you don't over cook your powder. just saying

Keep it up. No one else doing these videos on youtube.
Thanks we sure hope to!
enjoy watching learning alot from you
thank you!
Explain why your having Back Ionization and what you do to prevent it..better ground, back up away from your part, etc.
Great stuff. Glad to find your content.
Appreciate it!
Some great information on your channel well done and thanks
Thanks for watching!

Many Thnx! If only I'd seen this a week sooner =^( Great Stuff
Thank you
It is also important to spray electrostatic powder guns evenly
I'm using ion-collector, the special tool for electrostatic gun. Wagner's and Gema's gun are able to upgrade with this "collector"
Yeah, Gema calls it the corona ring, which grounds out extra charge in the field.
Can you use rubbing alcohol for cleaning
When you heated it in the oven to get rid of static electricity did you let it cool before you sprayed powder?
It was only in there a few mins so it didnt get over 150.
Thanks, just looking for advice. Really wanting to turn this into a side gig
What do you warm the part up to before you spray it again. Also do you let it run the full cure time on the second try can the original coat over cure ?
No set temp, just enough to dissipate static build up. I do full cure on second, wont harm base
So how did you fix the grounding issue?
it was error on application, to close to many micro amps.
What is your wipeall solution?
This was a wax and grease remover from Arnold's Motor Supply
I just did a part super chrome ll the second coat black chrome it fisheyed on me so I sanded out the fish eyes scuffed up the whole piece at 120 and recoated the whole piece flat black because I didn’t like the color it came out like bed liner... any tips on why??

what temp do you heat the part up to for recoating ?
if we just put a base coat on and are ready to spray the next one we let it cool to about 150 and then shoot it.
@@RightNowPowderCoating awesome thank you ! your videos are super helpful keep it up !
I didn’t see you ground it, do you have to provide a ground on the second coat if you preheat it?
Always ground the part, ours it at the bottom of the cart. Sometimes we do forget but typically remember real fast when we get shocked.
@@RightNowPowderCoating what do you ground it to if its a second coat, will it be ok to go on coating?
@@chipmcallister7349 I round to the cart it hangs on. Always use the same mount location on the part.
Also what degreaser is that you're using I'm afraid to put anything over powder other than soap and water lol
How does heating get rid of static electricity?
Good technical question, not really sure, but it does dissipate it
Your not worried about over curing that first coat by sending it through another cure cycle?
Nope!
I have problem With orange peel
lots of people do! make sure you are getting the right mils on....practice practice

That's a lot of work for an $80 chair
Xmas gift for my wife, also great opportunity to show people how to fix it!
