Paint should be flat, bright white. Ceiling paint is designed for maximum brightness and would be my choice.
If you are building the box from scratch, those sheets of cheap white particleboard/plastic laminate fake tile shower wall material are very easy to work with and clean. Home dePOT sells the plain white one for WAY less than plywood last time I checked.
stinkyattic Reviewed by stinkyattic on . Most reflective wood/paint OK, let's say I go to Home Depot to pick up some lumber. I'm building the walls for my cab inside a closet... What kind of wood am I lookin' for? Can I use regular ole' plywood? After I get the wood, what paint do I use? Glossy/matte? Any particular brand? Thanks! Rating: 5
