One word to the wise. If you insist on using your shop, buy some sprayable paint mask, like they use in booths. Spray the floor. When you are done, it peels right up.
We used to use it in spray booths and I think it was called PeelRite or Peel-E-Z. I can't remember which. But that was a few years ago. If you use a BC/CC, the paint will cover things but it is more of a dust. The clear will definately leave an overspray. Single stage will and does cover everything. Get a roll of Sharkskin plastic. It's about $35.00 for a 12' x 400' roll. It is the thin painters plastic. Use it to cover what you don't want painted. Workbenches, etc. One roll will last you forever.
