Interesting pics! I'm wondering IF this plasti-coat is what's on my spoiler. I noticed bumps in one area of the spoiler, then I could feel, "it's plastic coating". Without tearing things apart, my guess is; damage/rust and it was"coated" over, without proper prep work. This guess is based on a small area of rust, on trunk deck, where spoiler attaches. ANY IDEAS, based on this description?
