I've experimented with a few on parts and small repair areas. Rock-It seems to be pretty good. However, I can't seem to get a good answer on their effects in an overall painting situation. I understand that their intent is for production, but I also see a benefit in keeping down the dirt & possible bugs if you don't have a booth.

Jimmy, although most of the paint companies offer an accelerator, I personally don't think they are useful nor necessary. With today's solvents/reducers/basemakers/catylsyts/clears etc., all available for various temperature ranges, an accelerator is almost redundant. If you use the proper temp range materials, adding an accellerator increases the risk that the paint won't flow out properly and leave excessive orange peel. If I want the paint to dry faster, I just use the next lower temp range materials.

I stopped using accelerators when I stopped using synthetic enamels and RM StarRock. Yech!!

I like that loose paint. It can get you a great paint job. Ive never use an additive.0.02 cents
