Detroiters are beyond fortunate to have great LHS' - the tiny shop in Royal Oak frequented by gamers ( they don't sell car/truck kits ) has, literally, every single finish, shade, adhesive, spray, brush, tool, varnish, brand known to mankind.

Unsurprisingly, Gundam and fantasy sci fi lead military by quite a bit in customer interests, no surprise given the tilt of the OEs.

Point to story: Vallejo, AK and others have DEEEEEEEEEEEEEEEP catalogs of finishes, in both traditional and acrylics, dwarfing the older Testors lines.

In fact, I will be dropping a line to a few of the suppliers to suggest (if they don't already offer) automotive assortments.
