Found a good deal on a new (open box) Street Scene Spoiler for my GMC Sierra. The instructions say to scuff, wax & grease, prime with PCL 905 primer (2K) etc. The spoilers primer looks rough on one side like it has gouges. It doesn't mention anything about adpro but I did the float test and the piece indeed floats. I'm thinking maybe 220 DA to smooth out the rough primer, adhesion promoter, SPI 2K primer 4:1:1 (I'm out of epoxy), activated DBU base, UV clear. You guys see any problem with prepping this poly urethane part as described?
