I'm thinking about having the diffuser vinyl wrapped in black...

I spent a couple hours two weeks or so ago cleaning up this same issue. Clay bar did wonders for it dan! looks like a silver bumper again thank the lord

For some reason clay doesn't work in my situation...tried clay and nanoskin nanoscrub. Polish or compound and elbow grease is the only thing that works for me so far. I'll take pics as soon as it builds up again.

I notice that when I was at Z nationals washing my car lol...i was like how the hell did I get that??
