hi jimmo, could you give me an advice? i'm painting my motorcycle plastics, i made all necesary steps on prep, removed all paint to the plastic, took me about 2 months remove it cause is the first time i paint something, applied the adhesion promotor and 3 coats of black primer with a 1.4 nozzle and the finish primer was very very smooth, do i have to sand the primer any way? or just paint on it?
One last question: I have a Sierra 2500HD. The factory 'hard wax' coating on the frame is a POS, especially on the frame rails. I'm looking to replace it on the frame rails. Do you have a preferred 3M rubberized undercoating you recommend, or another product? I've looked at Duplicolor and POR 15, but passing on those. LineX can't be sprayed that low and at that angle. Thoughts? Thanks.
