So, as the title says my painted fenders have been stained from mud. We do take the Jeep out and play, but I also enjoy cleaning it. Mall crawler/Rock crawler, best of both worlds. Anyway, cleaning it today I noticed all the fenders were stained where mud had been sitting. I’ve tied wax, body shine, clay bar, white vinegar/water solution, everything. Any idea if this will wear off or do I need to have it wet sanded and buffed? Here is a pic. It’s hard to get one of it and hard to see in picture.
