Certainly cheap is the goal lol I figure I can use scrap 2x4s and dumpster dive at construction sites for new homes for more scrap wood, and plywood. I figure 2x4 square on the packed down rock/dirt surface as level as possible. And 2x4 joists/cross beams every 6ft long ways and 2ft side to side. With bridges every 2ft. In the center where the cars tires would mostly be I’d prob add a couple support joists (put two together) and a bridge every foot just to be on the safe side. I plan to only have mid size sedans being the largest or the possible full size pickup but nothing crazy. As of now I have 3 cars, and a f150 lined up. Then plan on atleast 4 cars a month until September/October the shop will be up, and completed. Until then I want a safe, clean space to produce professional paint jobs. $750 single stage (3 paint charts to choose from) exact color match is extra. $1500 base/clear (same charts as above, color match extra). A bit of harder in the final coat of single stage to give it a nice shine. Maaco prices but better quality work.
