Sometimes though it is late sunday, you are tiered, and have to chose between the bag and your expensive leather seats on your Porsche or Ferrari

After your long drive sunday night, even more tiered, you forget to wash...
Do you always have to lose the damn zipper to salt or rust even if it is a new boardbag?

Any experiences to share?
