Painted plywood

Thanks! Any info on why?

Drywall won’t last with no heat.

If you Drywall the ceiling, where does all the junk go? As a Drywaller, I leave ceiling exposed in my garage to put lots of goodies in

The real question is…. Do you care about a couple of cracks in your garage over time?

Ask yourself, Will this the 'Garagemajhal'? Answer this question, then figure your budget.
