Yeah, a random orbital polisher. Had no idea it had enough cutting power to do that but it was right on an edge. I had an issue on that fender a few months back and I think the guy who fixed it actually did some wet sanding there. So my guess is that it already had next to no clearcoat right there and I just pushed it over the edge.
Gonna get some quotes on fixing it and depending on how much that runs I might go ahead and upgrade to custom fenders like the Carbon Signal V1/V2's or the RS1's that Mr&Mrs used. Everything happens for a reason.
