PPg's tech sheets says not to etch over blasted metal and do not use epoxy over etch primer. the attatchment is a tech sheet on their dpx etch primer



That's not the etch primer paint I use, PPG I thinks it's DX1791 wash primer or something like that or I use Dupont Variprime which is the same thing, a little cheaper.

But your right, that etch primer advises against it, but wrong etch primer for blasted cars.
