I find Maguire's to be the best deoxidizer. Then Nu Finish which is a car polish not a wax and won't break the bank. Works great on glass or aluminum. I will wax once a year with Mothers paste wax or liquid on the vehicles or boat. My wife's 2007 Nissan has over 300,000 KMS on original paint and looks new, Canadian weather too. I can do a 4 boats with Maguire's deoxidizer. A little dab will do 4 ftsq. Small sections at a time and overlap just like you do when painting. I use a cheap Simonize polisher to apply, hand remove then use a soft pad to polish with the machine. Same procedure to polish with Nu Finish or wax. Remove polish, wax or Nu Finish with a soft Cotton towel. Do not leave Maguire's on for more than a few minutes before removing by hand. If you leave it for more than a few minutes it will not come off quietly. Nu Finish can stay on much longer. [links]
