Definitely. here's a pic of my daily driver from last year after only adam's wash and buttery wax. I have yet to hit it with a claybar, pc, swirl remover, and polish (all of which it is in desperate need of), and I can't wait till springtime to do so.
Wintertime here sucks for white and silver cars. The amount of sand that the DOT puts down on the roads could extend the beachfront by half a mile. The car still looks white until it snows then it looks grey LOL
