I am working on a custom paint job on a Sellstrom Brand "Phantom" welding helmet. The helmet has a silver paint or coating on it, and not much wants to stick to it, even laquer. Its just a plastic helmet, and just looks like silver paint, but who knows. Anyone ever deal with this, or know what type of coating they use. I contacted the company, and the guy they refered me to is "out".
Thanks in advance.

Get some plastic addhesion promoter at your local paint supply house.That always worked for me also sand with red schotch brite pad or 600 grit paper

Dave,
I got hold of the techies at Sellstrom and the silver coating is an automotive primer with a heat resistant additive mixed into it, not a plastic or painted coating.
Not too sure how I'd attack this one, but depending on the design, if it could be masked and scuffed prior to painting it, that might do it, as Ryan points out.
Hope this helps... Rapid

A guess would be HOK, but I wouldn't have a clue, except to say pass on the job.

My suggestion would be, be honest with the customer and tell them you aren't sure what to do. IF you decide to paint on this surface, you can't guarantee that it will hold up or for how long and leave the ball in his court. If he decides to let you experiment on his helmet, then you aren't buying him a new helmet if it doesn't work! Say hi to Kay... Posted by Ray Rheaume (Member # 3794) on :
Ok, now this one's bugging me....
Thinking it through, I'd try lightly scuffing the helmet and then hitting it with a clear coat. The clear might form a bridge so freehand lettering or pinsriping could be added after without worrying about the silver coming up into the paint.
Then again I could be completely wrong...any other suggestions? Rapid

I have a feeling that you may have to sand off all the silver finish!
Sounds like it has been modified to make it a "non stick" coating....in order to prevent splatter from sticking to it.
Just my 2 cents worth.

try Dupont's Mid-Coat Adehesion Promoter. It comes in qut. size. Spray on clean surface wait about 15 minutes an' letter. It works on Emron, it'll prolly work on anything.
...'cept those stupid plastic mail boxes . . . it ain't like that stuff is it??

Most high temperature coating achieve this rating by using a silicone additive, which is why even laquers dont want to adhere. A light scuff may not do the trick either, as the silicone is still there. Might try using a 'fish-eye' remover, as this is a modified silicone additive for paint, kind of like fighting fire with fire.

thanks to all who responded. the helmet is done and out the door. They are very happy with it.
I ended up scuffing it with a red scothcbrite pad, and then primering it with (don't throw rocks at me) Krylon Fusion.
The whole thing was then also painted with Fusion, and a little One Shot.
You can check it out on the portfolio page helmet pics

there's also a product called BULLDOG that we sometimes use here for plastic parts and have good luck with it. pick it up at your automotive paint store. mike
