I have used various brands of plastic fillers over the years. I have found that for the money Z-Grip. I sands eazy, non clogging and no pin holes(when mixed correctly). I also use the BLUE cream hardener. The red will bleed through primers.

I have tried RAGE, but, felt it was no better than Z-Grip.

I have used Dyna-lite and thought it was hard to sand, clogged the paper and had a lot of pin holes. Besides, Z-Grips doesn't cost that much more.

No better smell than that of fresh paint. I've been building and painting cars/trucks for 47 years. Not gonna stop now.
