I’ve been watching your Hands on Cars series on youtube and I wanted to do my 68 c20 paint process similar to what you did on the zed sled. My questions is the Eastwood Contour Polyester Primer says it is a direct to metal. I wanted to lay down an epoxy primer, do my body filler work, then shoot his polyester primer over that. I wanted to make sure there are no issues shooting this primer over the epoxy(in the appropriate window). I haven’t been able to find anywhere that it says you can do this other than direct to metal or fiberglass.
