 Now, are they applied with a sprayer or do you brush it on? Most are applied with, well, you can do anything you want. I do both. I spray it on and then I'll take a big wide brush and rub in or brush in and eliminate puddles or anything like that. Works like a champ. Right. So you can apply it in bulk, but back brush it or back roll it. Right. And then buy some Advil because your back's going to hurt.
