My 70 Dart

Anybody ever hear of 5 Star Auto body products? I was looking for some more surfacer, and ran across this at the little neighborhood paint supply. It's #5403 primer surfacer. 1:1 mix with either mineral spirits or acetone. Cures in 1 hr at 70 F. I had the door primed from previous fiasco, and wanted to use surfacer again. I've been using Icing, (great stuff), but at 20 bucks a quart it gets expensive fast. This stuff is $30 a gallon. Well, I sprayed this and I thought I may have dry sprayed it, but you can sand it in 30 minutes though. Maybe I didn't, maybe its the nature of the beast. This stuff if super easy to sand. Anything less than 320 is overkill. You'll buzz through it in no time flat. I'm impressed with it so far.
