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. I also don't care about how easy the product is to apply, whether it leaves swirls or not, how much it costs, or any of the other factors that normally go into choosing a product. Protection that lasts a long time is all that matters to me during the winter. What product(s) would you suggest for this purpose? Thank you.
