if SRP stands for super resin polish then please dont, it contains micro-particles or whatever, which im sure is great on paint, hell i used it saturday, but i wouldnt use it on gloss plastics, may look better initially but youre gonna scratch is more imo. Best use a a quality trim dresser, I have super dooper thick clear sludge but I cant remember the name of it at the moment but somethign like this should do:
