You might be well served to send a couple of the trusted and established members here a sample and let them field test it. With a good review you might get some good business. Some will be leery of buying with out a good reference from a trusted source. Just a thought. (and I am not trying to get a hand out as I don't yet have a boat)

After working with passivating techniques for approximately four years we decided to bring to market a product that can be easily and effectively used in the marine environment.
Thank you Spotless Stainless..
