I bought my Mr. Clean kit mainly to wash my truck because of its size but I am so impressed with the results, I think I'm going to try it on my Cobra. No bucket, no drying...no waterspots. Just stand there and watch it dry or go inside and take a nap while your car dries. Of course, the same rule of thumb applies and that is not to wash it in the sun. Late afternoon or in the shade is best.
