I am doing research for a company that makes a protective coating for the aviation industry and is now looking at the viability of the salt water PWC market. The coating protects both exterior (hull), and engine components. No corrosion after application. Applied by trained professional, like your dealer, it's only applied one time and it lasts permanently. My questions are; If works as advertised, would you have an interest? And would you pay $500 - $600 for the application? Appreciate any feedback. Thanks.
