If you haven't seen it in person it's probably best to forget about it. There could be problems a lot deeper than just the finish. Glass hulls that have had long exposure to sunlight can start to degrade to the point they are weakened. Used rotomolded plastic kayaks can be had cheaply new and are very cheap used. Since rotomolded kayaks are a relatively new product the hull shapes they have are newer too.

: I've been swapping e-mails with a CraigsList seller about an old-looking
: fiberglass kayak. Other than it being an Old Town kayak, he doesn't know
: how hold it is nor really anything about it.

: I'm curious to know what it would take to re-"paint" it? Ok, re-gel
: coat it.

: I've got no experience - I've never even owned a fiberglass boat!

: I assume I can get the kayak pretty cheap. I just don't want to have a ton of
: money into restoring it. Putting work into it, I don't mind.

: Any thoughts/opinions are welcome.
