nope, not the singer. The kind you rub on your paint. got so excited i just felt compelled to share... if you have wondered about doing this, you should go out, get some, and give it a shot. my paint came out unbelievable. wish i had done this sooner. also wish it had been 20 degrees cooler, but at least it was overcast, so i could work outside... anyway... there was a post a while back that had some links. one of the articles there peaked my interest enough to try it. glad i did. in the article i remenbered the author saying he used it on his windows. worked great. i have always had a stain (sumdgey, blurry spot) on my front winshield that no matter what chemical i used, refused to come off. well, its gone now! takes a while to get the feel of it, but after about a third of the car, i could feel when the clay was cutting and when it was just riding the film of (too much) water. one thing i did notice though.... once you clean with this stuff. EVERY paint imperfection shows up. it produced a mirror finish. if you have a 348 or a TR, you can expect it to be labor intensve on the cheese graters, but WTH, with the end result so nice who cares? try it!
