Automotive Paint -What can't you mix? How long can it store?

dp epoxy primer is a sealer, thin it out with some dt870 and your good to go, actually I always thin it no matter what coat it is.

They don't make Dp epoxy anymore, haven't for about 10 years. They do in fact make a DPLF epoxy which is Lead free. Being that it is lead free it lost a bit of pigment and doesn't cover near as well as the old DP. . I have always used Dp's 2:1 with no troubles.
