Rayman, that is going to be a really nice truck you're putting together. I painted mine in pieces and assembled onto to the truck over the course of a year. It's just about done with the exterior. Takes alot more paint that way. I've heard that if you paint piece by piece with a metalic color it's hard to get the same amount of metalflake on each panel and it might look like the atlas of the United States after it's assembled. john.
