PPG epoxy primer
I'm new to the body game and have a few questions that I need to ask. I walked threw the knowledge base and learned alot, but I am still unsure about the priming painting process. I had my 68 mustang media blasted down to bare metal. After I got it back, I wiped it down and a friend came over and primed it for me with PPG epoxy primer. Now my question is was that the right way of doing it, or should we haved layed an etcher down first. Also, I am now starting to do the body work and welding in new metal. I got everglass from the paint supply store, I put that on top of the welds and smoothed it out the best I can. I noticed that I get some air buble holes in it, can i use a two part glazing putty, if so what type. Finally after the patch work is done I plan to hit the area with the epoxy primer again. But do I need to use a sealer on top of that, or do I need to put the sealer on top of the putty then the primer. Last question, do I need to use a sealer, since I am using an epoxy primer, which I was told that water can not penatrate? Thanks in advance.
