Interesting. I have Linex on the outside, "shoe" of the boat. I added it last year across the bottom and up the sides about 6". I love it. It has been great so far. I was thinking about adding it to the bottom, under my floor boards. If you don't mind my asking how much did it cost to spray the inside? I think it is the perfect stuff... however, I don't know what it will be like in 10 years or so... that would be the only draw back I can see. Anyway, thanks for the response.
