Todd,

I use to shoot in my driveway, under a tree, then a carport. I'd rent a shop every once in awhile but that was usually when I was restoring cars. Most of my show cars were lacquer so the outside part did not matter much but with the base coat clear coat you got to be under cover. I still wonder how bugs and pine needles always find fresh paint and gel coat?

If you decide to build one I'll tell what I'd do different, lessons learned.
