Beautiful machine and decals! Love the red eye decals although I don't own any machines with that set.
If you use car wax, try in a small, inconspicuous spot first as a test. I have heard that any carnuaba (questionable spelling there) wax is good as long it is just the wax and not the cleaning/waxing compound stuff. I've never used it but have a couple of candidates to try it on later.
