Any professional detailers around here?
Awhile back I wanted to get some scratches removed from a door sill, not deep, but clearly visible in the clear coat. The detailer poured a little solvent onto a cloth and did a single wipe over the area and I got down to check on the scratches (idea being to melt the clear coat into the shallow scratches). The first two solvents he tried didn't do the job and on the third the smell was pretty strong, but it worked (the residual fumes were very unpleasant driving home). I'm trying to find out what that last solvent was, definitely stronger than acetone. Toluene? Something else?
