Has anyone tried this product on their Cobalt? https://topcoat.store/products/topcoat-master-craftsman-f11-polish-sealer-web-special-kits
I use it on my black 2016 220. Stuff works great. Keeps the water spots from setting in. Quick wipe after day on the water and looks good as new again!
I used it on a badly oxidized hull and it was ineffective at bringing back a shine. And I don't think it claimed to. Now that I have the shine back through wet sanding, etc. I may have to try it again. Members of another forum I'm on kind of gave it a "Meh...." rating. Nobody raved about it. Shawn
