I just shot some SPI epoxy on some 55' Chevy fenders and hood today. What is the time-window that I can apply body filler over the epoxy w/o sanding.
Thanks

So I am clear on this, I have a few questions. We can wait up to 7 days before applying the body filler over SPI epoxy? The process i follow when doing a panel is grind where my dents are, then 80 grit strip the panel. If I want to go and then clean the panel for epoxy and lay two coats down, shouldn't i resand the areas where i ground for my body filler? What if i find a dent i missed previously? Should I use 80 grit before applying body filler, or what? I have always put my body filler over bare clean grinded and sanded metal, followed by epoxy, so i ask what is the procedure to apply filler after epoxy?
It is best to epoxy all bare metal after proper cleaning. Even where dents are. I have seen rust under filler applied over bare metal. I have even seen rust under e-coat on new parts. Best not to take chances. Redoing it later takes more time than if just had done it right first time. We did 85 camaro in 92 with dp and good ppg paint using sealer even, and it looked good till 2012 when it was totaled and was not fixed. So it has stood test of time.

I think something that confuses lots of people that don't do body work professionally is the poor quality of your auto parts store dynatron bondo fillers. Last I ever tried, these won't stick good to paint & a featheredge onto paint would always fail for me..
The first quality filler I ever tried was the original evercoat # 400 2 part glazing, which I used on well over 1,000 residential steel door panels at a wholesale supplier in the late 80's. These of course had to pass for brand new with the only primer being matching rattle can lacquer primer. Never had any fail or get caught till years later some painter decided to strip one & found filler.
Good fillers become an integral part of the paint & primer they are applied over.
Although I never found any rust later on with spots sanded to bare metal & filled over on either steel doors or cars I did way back then, I won't risk that now.
