I've used it on my other cars. (Just got my Cobra, haven't washed it yet) You have to apply in small areas and don't really let it dry. Use the sponge to wipe on (about a 3 x 3 area), wait a minute, and start buffing with a microfiber cloth. I goes pretty fast and as smeredith stated, there is no residue. I've used the detailing spray also. It works good and only takes a few minutes to do a whole car.
