Dtm primer question.

So I’m gonna jump in...Everyone that says put a dtm epoxy over bare steel are dead on. PPG never recommends self etch before epoxy. Go with PPG vibrance series primer surfacer VP2057. It is a dtm epoxy high build that barely shrinks when fully cured, its a new product that hot rod guys are going crazy about. Don’t try to pinch pennies on the primer stage because it’s the foundation for your paint job. Just saying. Look up the info on ppgrefinish.com. I’ve used it twice now and it changed my world. Hope this helps.
