fishin fool,

You got me on this one. I'm no expert but I've had a glass boat for 20 yrs and have never had to do anything to it. I may be ignorant here, but why would anybody put Gluvit on the bottom of a glass boat instead of re gel-coating it if it needed it anyway? Maybe the gel coat was inferior or insufficient to begin with. Did he check with the maker? Sounds like an unusual case. I know the glass under the gel coat may be soft but so is the Gluvit if I recall. Does the stuff even adhere to glass? Seems like the stuff is used less for protection and more to help the tin slide. But if this guys bottom was torn up that bad with glass I suspect his boat would still be sitting high and dry on a gravel bar somewhere if it was aluminum instead.

And I thought I was hard on gear.
