My black plastic one piece rear deck grill was looking a bit long in the tooth after years of Calif. sunshine....I was going to paint it with a satin black spray but luckely my friend Rolf suggested that I try "Back to Black" (or equivalent) black trim restorer....It worked GREAT....It is thicker by far then armoral etc., sort of looks like...well, nevermind. I put it on with an old toothbrush to get in all the nooks & grannies. The grill now looks brand new & won't chip etc like it would have if'n I'd painted it....thanks Rolf. Just thought I'd share something that actually works........
