Where to Start, Part 2b

Where to start, part 2. Epoxy dry time.
It cannot be stressed enough how important this step is.  Epoxy is a very slow drying product.  It requires, preferably, at least 2 to 3 full days to dry before body filler or primer goes on top of it.  Preferably it should be baked as well, a lot.

♦️♦️If the epoxy is not dry, there is a good chance that it will continue to dry under your body filler or primer, and cause it to delaminate.  This doesn't always happen, but it does happen, and is not worth it.  This is especially true under polyester primer.
♦️Be very aware and very careful about how heavy any epoxy is sprayed and how dry it is under polyester primer.  
♦️3 medium coats would be normal when sealing bare metal panels to be body worked.
