Default Powder coating frame: will it stick?

I'm planning to restore a mildly pitted frame and a-arms, etc. I'd like to fill the pits to make a smooth surface. Will powder coating stick to areas that have skim-coat or filler? Or will the filler be "baked" right off the frame in the curing process?

If so, what are alternatives for uber tough and "correct" sheen/finish frame paint?

You can have the frame sand blasted, then use a d/a and a skim coat of filler to fill the pits. Seal with Eastwood's rust encapsulator. Finish with their chassis black.

If you do it that way, you cant have it powder coated. If it were me I would paint it, 1 sand blast, 2 self echting primer, 3 DP epoxy primer, 4 DP epoxy paint, This is a bit over kill but it will last a long time! My 02

They sell stuff specifically designed for powdercoating - I beleive it is called lab-metal. I still wouldn't use it, as it isn't needed. I had the same mentality as you, to make my frame damn near perfect, even get rid of the pits. I decided against using any fillers because I don't think they belong on a frame - but its your choice. My frame has lots of imperfections in the metal, but it still looks awesome and I couldn't be happier.

Besides, that's a ton of extra work on a part of the car that only you will be seeing when you are laying on your back. They'll never see those powder coated pits as you pass by at 100 mph!

I have been told that a product like All Metal (Evercoat) can be used to fill pits, and will still take the powdercoating since it has actaul metal powder mixed with the filler. I haven't tried it though, so you may want to check with your powdercoater.

Which is between 350-400 degrees for about 45 minutes.

And they can't powder coat anything, it has to be metal and electrically conductive.

Don't use the filler on your frame, it isn't worth the risk - even if you buy the stuff specifically designed for powdercoat. My powdercoater powdercoats glass - yeah, you heard that right, glass! Its pretty amazing what can be coated today. It is a special powder though.

yes you can powder coat anything that can handle the curing process and they have low bake powders right now! In the powder industry they are powdering mdf ,wood ect and that stuff is not conductive! just so you know I've been doing this stuff for fifteen + years now!!
