Had the truck for just a little over a month, waited for the paint to cure on the SnugTop. (Snug didn't recommend waxing for the first 30 days). Just washed and wax mine last week, using the Meguiar's Deep Crystal 3 step system. What a chore and then it rained 3 days later.
I've used the Meguiar's Endurance tire gel, IMO it's the best tire shine product out there and superior to the foamy spray can stuff. Meguair's will last over a week to two weeks and still be very shiny. After a month and cleaning brake dust off the rims several times, the tires still stay black, may not be shiny, but the tires definately will not turn brown. I've got lazy and stopped putting the tire gel on my other car and the tires still look great (black) for over 1.5 years now. However, there's a small annoyance with the Meguiar's Endurance tire gel... with the high gloss one, it tends to splatter if it's applied thick in some areas (esp. if it gets to the tread edges), and on a black or dark colored car, it's horrible, you get spots all over the sides of your paint. Usually, if the car sits for a bit it doesn't splatter as much or if you can find it, the low gloss version of Endurance, I've heard it doesn't splatter.
