I've been looking around for some answers to this but I can't find anything clear. I have the matte black shaker scoop and spoiler on my challenger and with South Florida's brutal sun i never leave any part of the car without protection. The paint gets Meguiars Ultimate Wax, and the rims get Poorboy's wheel sealant. Headlights get PlastiX. I'm at a loss for the scoop and spoiler as they are matte black and I've never really dealt with this type of finish. On my other car's I use mother back to Black , but I don't want the area to be shiny. Additionally Back to Black seems to stay oily and doesn't really dry. I don't want any Back to Black on the rest of the car(painted surfaces). My question is, what do you guys use for Matte Black finish? Will regular polymer was do the trick to protect? What about the vinyl stripes? I've heard some people just leave the stripes alone and others say that coating with synthetic wax is ok.
