I bought a gallon each of Benjamin Moore Fresh Start primer and Aqua Pearl satin finish top coat, both premium grades, apparently. It will take a few weeks to get the whole shop done as all the stuff on/near the walls will have to be moved. It's a good thing that the electrical outlets and lights are on different circuits. There are quite a few outlets (with conduit) along the wall that will have to be moved to paint.
On close inspection the wall is a little rougher in some spots than I'd thought, so it seems like a good idea to start with one small section and see how well my surface prep works.
Thanks (all) for the advice.
