I'm throwing this question onto the Mud in hopes of preventing rust on my 60. I live in Colorado Springs ,CO, The city is raising the salt content from 6% to 20% in the sand they put out on the road come winter time. Any suggestions on how to prevent/minimize the effect this will have on my truck. As of yet I have very little rust and would like to keep it that way(I think it has been in Co from the start not sure though).
