Oh geez! a grinder! oh well, you may be better off doing it yourself. be careful of
those isocyanates, wear a breather. When you say "sandblasting" I trust that you
were careful not to get the metal too hot whilst in the process. This is often the
demise of smooth steel panels as the blasing with, any media really, can warp the
panels irreparably. Did you use a flint shot recycling miniblaster? That is what
I'm thinking would work well. PPG does have a zinc chromate primer which might be
worth looking into to apply as and undercoat before the DP50. Oh and be sure to cut
your refinish material with the proper heat range specific reducers. Air movement
(preferably fresh) is critical more so than heat during the curing process Good
luck.

If you are doing the whole van, R+I the windows, rubbers, handles, lamps etc. It is
not worth painting again when you go through the no touchee car wash and see all of
your refinish material around the tape edges blow off and go down the drain. Enjoy.
