I' m with you on the Dc92. The stuff is nearly bullit proof. We started out using DC88 then DC89NR when the VOC regulation started being inforced in our area. Stuff buffs good fresh or wait 2weeks and it is OK. I have been using Nason's 4:1 panel repair clear at the shop at home, when the temp outside is under 20. It drys good and is really buffable. Worth a try for those of you that are painting in cooler climates in at home shops. Very forgiving for the novice.
