If it"s just cheap ole rattle can paint, try these.
Fine steel wool & little elbow grease. Easy-off oven cleaner, or no name brand type. Use to use that for removing logo, lettering, from vehichle.
And one that has worked, and sounds crazy, use the same paint you sprayed with. Spay the area over, and while wet, wipe with old rag, to remove both.
The solvent in the paint, will help loosen the other!
Since the clear coat finish they used at Win, wasn't scuffed, it should come off easily. Harsher solevents could be used, just don't leave 'em on long.
