I really like this thread alot. Good find and keep trucking on the build. Since you are on the cheap, and you said you have a plan for the wood grain then you may want to consider Krylon Fusion. I'm not sure how all the paint is but a guy at work painted his samurai for about 35 bucks. It looks great, he just took his time and sanded a bit. The paint may be fine but its always an option. Something that I saw once that looked amazing was those factory wheels you have painted white. With all the spokes it looked really good. It was on a maroon FSJ as well. Keep up the good work.
P.S. are you building this expo rig for missionary type work?
