On our last trip I ran over a huge piece of tire on the freeway. Luckily, it didn't do any damage to the boat or trailer, but it left a four-foot skid mark down the side of my nice, white trailer. Any ideas for getting it off?
Yes, I would think that brake fluid would damage the paint. You might try acetone; available at hardware or paint stores. It removes a lot of stuff harmlessly. I would still test it first though as the labels always say....
Sounds funny but use a deck shoe or K-swiss style white sole shoe and scuff it along the mark. Should take the black right off. Works on the floor anyway.
