Up north here I slather the chassis in krown / fluid film. However ive decided this year im not buying any more products that are going to sit and go bad on the shelf. I have good QTY of seal and shine, and well as lots of 476s paste wax. With the fact I will NOT be washing my car during the winter, other than rinsing with a hose to get most of the accumulated crud off, which of these two would you want on your car for the entire winter?
