I know ceramic coating works well for boats once the surface is prepped properly. Has anyone added a coating to their Oliver? I'm thinking about this one. http://www.modesta.co/product-bc-04-nano-titanium-glass-coating.html I have done a few cars through my local installer in this product, and he seems to think it will make a huge difference in keeping it look as delivered. I have had it on one of my cars for 3 years and it literally looks brand new, sitting outside all day, all year long, in Florida sun. Its not cheep, about $3000 for the Oliver II. It's not like money is no object but time is.
