One thing is for sure it's not going to be any cheaper with Gluvit all over the bottom. If you can even find anybody to touch it in the first place. But then again I suppose there is always someone that will do it for a price.

Fishen Fool, it's a lot of work but you’re buddy will probably want to get as much of that stuff off himself before he has someone work on it. Most of glass boat fabricators out there are good dudes and will steer him right. Ron at Lavro is a standup guy who is very accessible and really knows his stuff (I think he has glass in his blood). I'm sure there are others in your area. Might ask Clack? Worth a call cause right now because from the sound of it that boat probably isnt worth much the way it sits and its heading south fast. A glass boat without a good skin on the bottom is like a barn without a roof; it’s only a matter of time before it’s trash even though it could have stood for years. The good news is, if the glass integrity is not compromised, a new gel coat on the bottom could basically make that boat whole again and it can last for many more years to come. Although I have never used the stuff myself, I think there is some easy applique gel-coat on the market. Marine Supply stores (Fishermans, Boaters World, etc) might have it. They might also know of some easy way to remove Gluvit too. Maybe some other guys on this board have some experience and suggestions for you, but personally I wouldn’t do anything without talking to someone like Ron who really knows glass DBs.

Fishen, I’m sure your buddy will greatly appreciate your offer to help. Myself, you know I’d like to help too but I have a deck to replace, a house and barn to paint, a truck to overhaul, a list of honey dos that just don’t end and……………..well you understand.
Best of luck and happy drifting.
