I got a tip from a friend to try out the new Meguires Tech Wax along with micro fiber towels.
Wow this stuff is unreal.
I bought the liquid version (there is a paste available) at Wal-Mart for just under $14.00.
I bought micro fiber towels at Costco (16 for $9.00).
I waxed the Durango and about half the Mustang in only about 1 1/2 hours.
It spreads on very easy (comes with an applicator sponge) and wipes off even easier. The shine is unreal, it makes the paint look really deep, and wet. Almost like a new paint look. The color of the Durango really pops, and I think any color with lots of metalic would. The Mustang's black looks incredablly deep.
I would recommend this stuff to anyone
