I've sprayed wheels and brushed a bicycle frame. Brushing unthinned Plasti-dip didn't work out, but for spraying there's Plasti-dip S. It has more toners.
My intent is to undercoat my panel van with it. Someday when it goes un on a rotisserie and the media blasting and finish paint happen, it will just peel right off.
My thinking is—lay it on thick:
Cobb -- bedliner is heavy, Plasti-dip weighs almost nothing.
