Anyone ever try this stuff? Does it really last a full year? I dont know if I would trust it to go that long.

 

Refer to your avatar image for the attitude of the typical car owner who uses this instead of a high quality regular wax/polish system. This is sold for the people who are NOT intending to regularly care for the exterior finish of their car.



Like me. It did good things for the black exterior trim . . . when I cared to use it. Then I lost the bottle and let's just say my car probably gets waxed somewhat less frequently than some of our other members' rides.
