My back one is black and the front one is a goldy colour will take some pictures tomorrow if i can. Just a word of warning DONT take the plastic off the metal fixing strip if you paint it as for some reason the plastic srinks as I found out to my cost and you cant find replacements
I did wonder about how the plastic would be affected by painting, especially now it`s aged and weathered.
I wonder if there`s any special paints for plastics?
I have noted that these infills are rare to find now.
Try a little green scourer dipped in gunk for the "black" rubber in-fill. Gently work away and the rubber goes back to plack and becomes slightly more supple.
Would it not be better to just give it a good clean with Autosol vinyl and rubber cleaner? Or maybe that black plastic polish stuff you uses on modern bumbers?
