This is my first time with 476s but not my first time for paste waxes. I've never run into any layering issues except if I didn't let the previous coat dry completely or didn't set with water I'd get a streaky look that required lots of buffing. Those pseudo holograms from the residual oil are easily taken care of with water, in my case distilled water, since I keep a spray bottle of it for my
M105 polishing technique. I often wax in the hot sun too, polish in the shade of course, since I like to make sure the wax dries completely. Never had any problems with it sticking to the paint. It always let go with minimal effort I attribute this to smooth paint. I did find that during subsequent layers of 476s that the wax came off easier and easier, although getting all the residual oils off did take lots of buffing, turning and more buffing of the cloth. No hard pressure to cause marring. I think it's due to the cellulose sponge putting a much more even and thinner coat of wax then comparable foam applicators. Foam applicators don't retain as much water as cellulose so I find that they don't coat quite as evenly as good ol' cellulose.
