Okay well it's all done.
The first thing I want to say about doing this kinda of job is
you get what you pay for, spending more time on prep will definitely help your paint job but a rattle can job is still a rattle can job.
Painting my Jeep from black to tan took about 22 hours total. Out of that 22 hours 90% of the time was spent sanding the Jeep. The process was sand, wash and sand the shiny parts. My goal wasn't to take it down to bare metal but to just break the clear coat and use the original paint as a base. I broke the clear coat with 220 grit and once all that was gone I ruffed up the original paint with some 180.
Painting the Jeep was the easiest part but the two problem areas I had were roof and the hood. Being the largest surface area. It took about 9 cans to do the first coat, after the first coat was dry I washed the Jeep with dish soap and a bone sponge then sanded it with 600 grit. After that I washed it again, same as above. The 2nd coat definitely made the difference, being originally black the first coat didn't hide the color well but the 2nd coat really brought out the desert tan color.
For the lower portion of the Jeep I used Dupicolor bed liner and this stuff sucked! I will not be using it again for anything. The reason I chose it was I wanted something that would be thicker than paint and hold up better. I wanted the thickness of the bed liner because the lower half was in rough shape and I wanted to hide that as much as I could. However this stuff sucked at bonding with the tan coat. I sanded it down with 180 before hand to try and let the bed liner adhear better but it just didn't work out that well.
If you are planning on doing a rattle can job don't be afraid to do it! I read just about everything I could find on the process and talked to anyone that would give me advice or tips on a DIY paint job. I would like to thank Eric from
http://www.ericsxj.com/ his write up and final outcome really pushed me over the edge with doing this, although I don't think it came out as good, I am proud of the job and I did and think it is in the middle of all the rattle can jobs I have seen on here.
If you have any questions feel free to ask.
