Deano:
What do you mean when you say that "Zaino is more a pain in the a** to get started on....." ? DO they suggest stripping all other waxes / products off your car's finish before applying their product? I went through that while trying Griot's "Bets of Show Wax". They said their product wouldn't bond to other waxes / polishes that contained silicone so it had to be stripped off by using their "Paint Prep". I went through that entire procedure (stripping / cleaning then polishing w/ Griot's polish, then waxing with Griot's wax, etc...) and didn't care much for the results when all was said and done.
BTW: DO NOT use Griot's "Machine Polish #1" on your clear coat finish!!!! I don't care WHAT they say....it will scratch the $hit out of your paint. ....Luckily I used it on the wife's car (in a small area)before going to the Cobra. It took me weeks of going over it with a finer polish to get the scratches out.
