Advertising at a carwash

[psdnate]

Has anyone done this? If so how did it work for you? I know a guy that bought a carwash over the summer and I was there this morning washing my truck and came up with this idea. I havn't said anything to him yet. I wanted to get peoples opinions. It's 4 bays with a truck bay. All do it yourself and there are a few vacs also. No advertising is there now.

haven't done a car wash. I do have 14"x18" signs at a couple of Dunkin Donuts. Those have yielded a few installs and 20 or so irrigation blowouts this season
