qwertydude- I'll be interested to hear if you run into any layering issues. It's only happened *one* time for me with 476S, but when it *did* happen the resulting pseudo-holograms were a real PIA to buff out without causing any marring. Every other time I layered it things went smoothly, but that one bad experience really made an impression on me.
Intersting that you get a finish you're happy with using only the
M105 (I can never really evaluate such stuff from a pic but if you're happy with it that's all that matters IMO). I always find additional burnishing/jeweling types of final polishing to be worthwhile, but hey, it's just more YMMV stuff.
sweetlou- 476S should always be applied with a damp applicator. I never find any big difference in *types* of applicators, so I'd recommend you just use whatever you like (but use it damp).
