What sealer or wax product would you recommend to give maximum protection to a car during the winter months without regards to shine? Winters in Northeast Ohio and tons of road salt can be rough on a car's paint. I'm looking for a product that will have maximum durability and I don't care about how well it shines. If the car looks dull all winter that's fine with me. Protection that lasts a long time is all that matters to me during the winter. Any suggestions? Thank you.
