once i get the patch panels welded in the firewall and the udercoating off of the inner fender area , what should i clean the metal with to get it ready for paint ?

i used AIRCRAFT stripper in some areas of the engine bay and alot of it plus KEROSENE & PAINT THINNER/MINERIL SPARITS for the under coating on the inner fenders .

i want to be sure im on bare metal before primming & paint . so what steps & products should i take and use to clean the metal ?

thanks RANDY

The stuff is called vinyl wash or metal prep and you put it on with a rag in one hand and take it off with a rag in the other hand. It`s an acid solution, very toxic, wear gloves goggles and a mask and DO NOT GET IT ON YOU. Then you wash it with either diluted water or you use some kind of thinner it`s been a while. Then use a tack rag.Then you prime it with Epoxy Primer, wait half an hour window time and the hit it with Polyurethane Primer. The reason you hit it with Epoxy Primer is because it is bare metal andPolyurethane primer will not stick to bare metal. :beer:
