I bought this bonnet sound proofing for my XR2 off eBay. I tried to clean the marks of it but they won't come off. I was thinking of spraying it to make it look better. I just wondered if anyone else had sprayed there's? And what paint they used? I just don't want to ruin it so thought I'd ask on here. Plus because mine didn't have one on could anyone tell me what clips to use? Here's some photos.
