My arctic white c7 has sustained a bird stain on a 3M Venture Shield Bra, and I have not been able to remove the stain. When I often get these stains on the paint they easily clean off as long as I do so in a timely manner. However, even though this stain is on the plastic bra my corvette is arctic white and it is noticeable. I have tried every cleaning technique I know of including hydrogen peroxide to no avail. The bra dealer knows of no chemical. He says is can repair, but the repair edges might be worse than the stain, and the cost of replacing the whole bra is not worth it. The stain is brown and only 2mm in diameter. I am presently trying to sun bleach the area. Does anyone out there have any other ideas or experienced a similar situation?
