Drove the cruiser to work yesterday instead of the Tundra, it started snowing and the salt trucks were out and about. Commute home was 28 miles and all that salt and chemical must be all over the under carriage. I just winterized my house so all the hoses are put away, water turned off and i can't get to it until this weekend. Can't go through a carwash because my roof rack would get torn off probably. How much time do i have before my clean under carriage starts to rot away.
