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?
