Getting the raised floor for the paint shop opened opportunities for more storage. The wall opposite the spray booth contains the tank for a toilet, and so, it is built of 6″ studs. My plan is to fill in all the voids with shelves and storage. The first module, designed for spray cans and other paints, and made from scraps found in the garage, is now installed. I put wax paper on the shelves because the paint was taking forever to cure!
