I wasn't happy with leaving the foil insulation exposed...it just looked too unfinished...
Priced out plywood...then have to paint it...
Decided to go another route using white Masonite....muuuuch better...
I added recessed blocking in the wall for a an old 3' x 7' door I had as a countertop. Then capped the ends with a 2x4 to keep things from rolling off.
With 24 1/2" deep base cabinets left over from the kitchen I still had a gap behind them so I built shelves that are 7' long for storing trim and roll bar tubing.
Then added 3 wall cabinets above...
The Masonite is the same as the white pegboard...I bought one sheet...cut it down and installed it where I needed to hang tools...
