Washs and waxes STUFF THAT WORKS

It would be nice to have someone who actually knows chemicals say what works and what doesnt. I've been using meguires(sp?) gold class paste wax and cleaner wax forever. Iv'e been living in WA where the weather tends to do a number on paints and wax's though. I also wash my vehicals religously atleast once a week if not 2ce, with wax done every weekend or other weekend...I had to do body work on the rear bumper of my truck last summer and did notice I had to sand through alot of wax though lol. Not sure my opinions worth anything, because ive just based it of of what i percieve works. Zymbol i've used a couple times and seemed to work, well like wax, havnt really noticed one wax being better than another. Though im sure there are some out there that increase survivability of paint, and probably a few that because of certain chemicals harm your paint more than help but i dont know enough to say which.
