i have run many homemade peices on my skis for over a year and i ride 100% salt! Powder Coating is much stronger than any paint. I will agree that its GOING to eventually rust, but i'll ruin the fiberglass ski and pole a few times before the mount goes. If someone wants to pay a little more i will make brackets out of stainless steel (TIG weld too), but thats going to be the same price as most of the competitors in the end
