Brian hit it right on the head. You are going to spend alot of time and money on a paint job. Why would you want to skimp on something like that? You want that area as clean and dust/lint free. Let's not buy something that is basically all lint for that area.
Reminds me of an old boss of mine. There would be a lot of money in used sandpaper on the floor, and he never really complained about it, but he would go around picking used paper towels of the floor which were maybe a buck or two a roll and want us to reuse them. Never could figure that out.
