Doing Bodywork on my own car need some assistance. Please

Correct. What I mean with do your body work over 80 grit, after you spray you epoxy any spot you need to do filler work DA with some 8p0 grit first so there's some tooth for the filler to grab on to. The most important thing to do though is read the instruction on the cans and tech sheets.

Thanks ADAM. We are having a real issue with finding someone to do the work. I like the idea of doing my own work, so I am looking at cheap guns to spray the epoxy on with. I have read some reviews of the HF guns. They are cheap and this is just to spray the epoxy on. What size tip would you use? They have a real nice HVLP gun, but it comes with a 1.4 tip. We have a 30 gallon compressor 2hp 135psi max that we could use. I know its not ideal, but I am fine with doing panel by panel so that it doesn't run out of air. What do you think of this idea?
