The only solution I can offer is the one that I used to resolve this issue permanately. Move south! The day we left Buffalo, NY the VERY LAST thing I did was stick my shovel in the front lawn (in August) and gave it the one finger salute, got in the moving truck and gave it more one salute for good measure. This is a true story. Now we drive our classic car 365 days a year (litterally) and no longer worry about the "s" word (snow, salt, slush, sleet and any other crappy "s" word you can come up with).
