Never done it, but it probably wont hurt anything. Heck, Ive seen little patches of wax left on after sitting for a week or so with no ill effects. It shouldnt take more than 20 minutes to do the whole boat anyway. Start waxing on one side and finish on the other side. By the time you get done with applying the wax, you can start wiping it off. It comes off much easier than applying it. Thats one of the good things about ProTec.
