northerndave . . I use epoxy for my blocking. As long as the epoxy is one that likes to be sanded, I have good results. I like it because of not having any isos too. I use Kirker, which builds well and sands well. If I need something that has more build, I use Polyester primer. Then I follow with epoxy. Polyester primer, no isos again. But 90% of the primer I spray, is epoxy. I normally will spray 5 coats for blocking.
