I had a question regarding the best step after initial filler/blocking. Once I have the panel down to bare metal I will spray with epoxy. Block the epoxy to find the low spots then either hammer it out or fill it. If I was to get down to bare steal again should i respray the epoxy before moving onto poly surfacer? My guess is yes since the epoxy is what seals the metal. If you can help me that would be great.
Since the Contour Poly primer can be applied direct to metal you can actually go over the mixture of bare metal an and epoxy with no problem. This would save you a step and not have to apply additional products.
