The vp2050 is the way because it offers excellent sand ability and is dtm and barely shrinks. Slam 2-3 coats with 15 minute flash in between coats. First few swipes over the top to remove its semi gloss look and it sands like butter. You may even be able to skip the 2k primer surfacer that is urethane based. I’m gonna lay down dp50 over raw steel then once the body work is done over the epoxy I’m going to slam some vp2050 as my surfacer. Let us know how it goes.
