I plasti dipped my Xterra a few months ago (just acquired my jeep) in OD green,
It took me a day and a half to do it completely by myself... I wish I'd have had someone else to help me though. the body had about 4 coats or so, the rims had 5, as did the bumpers/roof rack.
If you are going to do it, take your time. tape off EVERYTHING, don't get lazy (I did) even with my laziness it came out really nice. I did not disassemble parts as I should have, as I was alone, and only had a few days off of work. I also DID NOT thoroughly clean any part that I dipped, the rack, rims, and bumpers were dipped for over a year, held up perfectly.
Some hints- Don't do it by yourself if you can help it (unless you have alot of time), Don't do it when it's windy, ORDER MORE PAINT THAN YOU THINK YOU'D NEED!!! (I ran out when I was about 3/4 done, the roof remained yellow for a few days.), don't rush, I had to redo a door because I wasn't paying enough attention and the pain ran on me. Hope this helps, if anyone needs more info I'd be more than happy to help.
