DP90LF

[YENKO DEUCE REGISTRY]

I've only sprayed PPG so I wouldn't even know another brand to shoot. Also, I have the DP90 and K36 - so maybe just shoot some 90 and then some K36? I have some Deltron single stage gloss black too, could shoot that over the K36 and be done with it - but was hoping to get it in a dull black primer so it would be ready for whatever color Danny wants it to be as I'm thinking he might get Amanda's car when she moves up and Danny ages in. (this car has a standard footbox, so if the kid gets taller than 5'8" or so they get a bit cramped)

While I'm not that familiar with ppg other than dp, I don't see you having an adhesion issue with K36 over fiberglass. It will cover any color variences in a couple of coats, give you some fill build, and save the cost on the dp. If this was a metal body, I'd say go with the dp, but I think your ok with the K36. JMHO
