Plasti Dip for rear "S" spoiler refurbish
My rear "S" spoilers and rear bumpers were badly sunburned and weathered, so I've been searching for a way to repair them. Various methods have been mentioned (bedliner, paint, vaseline, BacktoBlack) but not a conclusive answer I could find. I read somewhere about using Plasti Dip for rubber spoilers on BMW(?) so thought I would give that a try.
First was to give them a good clean using wax and silicone remover. This actually melted the surface some - the rag came away very black, and dried stiff with the residue. I used 80grit sandpaper to scuff all surfaces, and feathered in the bad spots where the original smooth surface was gone, revealing the foam underneath. I didn't use any fillers for the bad spots, not sure how they would blend, and figured I could just build the spots up with the spray. Found out next that the spray is actually very thin - not a thick build for each coat.
So armed with black Plasti Dip in the spray cans, did the bumpers first as they are less prominent if this didn't work out. These got a light 1st coat, then 2 more coats applied so it was wet appearance, with minimum 30 minutes between coats per the instructions. I think they came out great, and hid the old weathering really well. I waited 2 days for these to cure, then installed onto the car - a great improvement! The surface of them felt like new rubber with that grippy, flexible feel.
The spoilers had more damage, so more to fill in. I applied 4 coats total to the spoilers, with the second coat having extra in the bad patches to try filling in the "holes". This spray is very thin - much like spray paint, so don't expect it to fill areas like a bedliner would. These could probably use another 2 coats to fill the worst spots more evenly. From what I've read, it is no problem to add more coats later on, but for now I'm pleased with the results. I waited 6 days before handling the spoiler parts, and had them in the strong sun for a day after spraying to help cure. The sprayed surface was very flexible, standing up to the extreme pulling the get the 2 hidden screws installed under the side wing spoilers! After I had the spoilers on the car, gave everything a wipe to get dust off, and found the dry rag I was using can scratch the surface, so must be careful to use wet cloths for wipe down. Total job took 3 cans of spray. No affiliation with Plasti-Dip, just an impressed first time user.

That is exactly my experience as well (rims). Have you tried their product to clean brake dust from dipped wheels? They claim it works really well but I was skeptical and didn't get it. However, maybe I should give it a try.
I think I may do this for my spoilers though. For some reason I had never considered it...

I used black rubber bumper paint on my 77 mg midget from ace hardware. I used the primer that is sold with it and it came out really well with a nice low gloss sheen. The US midget used rubber bumpers.
