Just ordered some P21S Wax, I am going to put it on top of 3 or 4 coats of UPP. How long do you leave P21S on and can you layer it? If so how long do you Wait?
P21S CW is like on/off, apply - remove. One section at a time. If you let it dry it'll be difficult to remove. You should put a coat every week to month or so. No reason on layering on a short period of time.
