On my own car I wax it probably every other wash which comes out to ever 2-6 weeks depending. I either use Dodo Juice SN, BFMS, and now I'm going to try Supernatural Hybrid. I love waxing, and I love the look of a freshly waxed vehicle. I never take waxes to their durability limits on my cars. Now for my wife's vehicle it had been getting Collinite 845 twice a year, and will be getting opti-coat sometime soon. I hate working on it, and it's white so there is no pay off at all...lol
