It is pro grade, store brand. I'm told ppg. High build primer that I added flex to. I guess I've always used rattle can guide coat. But I'm no professional. I hear you on the rattle can stuff through. I think it was part of my earlier problem. I'm gonna use the adhesion promoter on my bare spots, make sure there is nothing shiny, and hit it with another couple coats of high build. What do you like for guide coat?
