For those that do this, what is better, spray on or brush? There was a company that came through our area and I think they took some customers of mine (older people) for a ride. They just sprayed the asphalt, and didn't brush it on. They didn't even blow it off first. They sprayed over loose stones that were there, too. I've been told that brushing gets alot better coverage, and it seems like it would. Any ideas?
