Can't agree more with the prime it first comment. I primered w/ the typical flat drywall primer, the drywall and mud really soaked it up. Just kept pouring it on. When I painted a semi-gloss coat it went on so easy! One coat and it looks perfect, not what I really cared about since it is a shop, but boy does it look good. With the exception of the primer, I bought all my paint at a used building store, called the Re-Store, they charge $3.00 a gallon for unopened paint and $2.25 if opened and used a bit. Great bargain and whats wrong with paint dated less than 30 days? woohoo, what a deal, I'll guess most towns have something like this at a recycle center.
