Silicone containing wax compounds can only be removed by stripping, and even then some may remain. Silicone waxes drive body shops nuts. Sanding usually only spreads it around. My brother threatened me with bodily harm if I waxed the 280 SE, since it MUST be repainted soon -- the nasty cheapo job is nicely peeling the factory paint up on the deck lid!

Even carnauba wax can be a problem, paint won't stick to it. Fisheyes are bad enough, non-adhering paint a couple years later is worse -- no one likes peeling paint.

Petroleum waxes are suspended in organic solvents, but they won't harm the paint. They can also be removed very nicely with wax removers.

The one thing to stay well away form is the wax at the car wash!!!!!

Whatever "system" you decide to use you should stay with, mixing manufacturers products could be a problem.
