PAR Posted May 13, 2018 Report Share Posted May 13, 2018 Using neat, pigmented epoxy as a primer is as costly as a good primer, plus it's a lot harder to fair and smooth. When you put pigments in epoxy, you don't get a paint like finish, as it's generally translucent, not the solid color paint produces. Of course, multiple coats can get you a solid color, but this is even more work and materials. Naturally, it can't be done as a top coat, as the epoxy will still burn with UV exposure, just more slowly then a straight neat coat. Lastly, the thing with primer is it makes a uniform "tie coat" for the top coat and can change the look of the top coat as well. For example if you paint a red over grey primer, it'll look warmer then if it was painted over a white or black primer. I'd much prefer to work primer than a neat epoxy coat, FWIW.
