I redid my 83 Scrambler starting about 4 years ago. I took her all the way down to a bare frame and built it back. Took me 2 years and I finished up with about 12K in it in materials (original budget was 10K). Stripped all metal down to bare, patched by welding for frame and some body holes, and some bondo work. Primed and painted everything. Replaced ALL bearings, swapped gears, new brake components, rebuilt motor, new seats, console, LED tail and turn lights, redid dash lights, recolored dashpad and door panels, rebuilt doors, new radiator, swapped transmissions, new master cylinder, and added AC.
I painted it myself, well had help from some friends who have painted autos, and equipment for years. We got good paint, and it is holding up nicely. Couple things I did to cut costs on the paint that have worked well for me. My sealer was darker than I liked (super dark grey, almost charcole). So as I was doing a tan/yellow color, I got a can of white tint and did a base coat with that to keep from having to have a second gallon of mixed paint for a second coat. I saved paint on the bottom by using some rustoleum that we mixed for spraying on the undersides. The almond color is real close to the color I went with. We were able to do a few coats of that super cheap to save the good paint for the visible parts. I've since played with the rustoleum and added a touch of yellow to it to be able to spray my gas can and console to match the jeep. I even used it to spray my military trailer to match the jeep.
Be a little realistic on prices. Best bet is to plan out what all you want to do and put a spreadsheet together with costs, quantities, and totals together to plan with, then track to those how your are going. There will be things you run into that you didn't plan on (or think of) as you go, so expect to run over some. I underestimated sanding supplies and bondo needs, as well as a couple of bearings I didn't realize were bad. I had a good build thread on the CJ8 forum, but since all my pics were on photobucket, I'm not sure how much help that will be now.
