I'm not quite that subtle.
Its pretty hard to do any damage with a PC so I would prolly hit it with
DACP or even Diamond Cut to get the scratches out nice and quick.
I hate beavering away madly at some damage and not making an impact!
Its a waste of time and effort.
Anyways.
Once theyve gone, build it up with something like
AIO topped with a glaze and S100.
I would say UPP but on a garage car it's a little overkill I guess.
