Road Salt
With my 01 CLK 430, I got a full undercoat, trunk, hood and door treatment for $250 and it comes with annual renewals.
I also rinse the underside and body panels with water (usually luke warm to keep from freezing) when my car looks salty (about 1x per week)
I'm also from CA and will return one day. I love my CLK and want to bring it back to CA with me, but not if it's all rusted out.
