Epoxy primer

My opinion...Depends on how long they are going to set...if its going to set a few weeks I would epoxy them. If your going to hi build prime them tomorrow I would skip it until right before base coat. I really like epoxy primer (DP90) i'll use it right after I do my body work then i'll use a high build primer block it out then use it as a sealer right before my base coat (wet on wet) spray the epoxy once it flashes over go right into base
