ive been using the MM lacquers for awhile too...i use the PlastiKote white sandable primer on all of my cars and the only problem ive had out of the MM paints is the Mopar Plum Crazy...i painted a 71 GTX with it and wasnt happy with the results...soaked it for 1 week in CSC and it didnt budge the paint a bit so i ended up buying another kit...other than that i have had no problems with their line of lacquer paints at all but i mostly use Dupli-Color automotive paints
