How to patch an old plastic canoe

I've got an old Buffalo Canoe, which is I guess the old Blue Hole mold. Anyway, it is cracking on the bottom where the sides turn up. Has anyone got a good fix for this? Can I just fiberglass it?

I recently heard of something called "Rec Repair" might be worth looking into.

If its the right kind of plastic there are places that can weld it with plastic.
If not clean the area and rough it up with sand paper. Then heat the area with a heat gun or hair dryer. Get it hot but not soo much that it melts the plastic. Then apply multiple layers of duct tape and press it on firmly with the back of a spoon.
This method works really well on plastic. I even have an aluminum canoe that had a puncture and with this repair method and its held up for 6+ years

Interesting stuff - I'm going to have to get at least one sample to experiment with.
I've seen some pretty extensive repairs with fiberglass, so yes, I think that would work.
I'm leary of welding repairs; don't know how that would work with the ABS foam core.
I'd send a PM to Painter Bob or call Moore outdoors and see what patching methods have been used with any success on rental canoes.

We (Byron and I) have done a similar repair to a Prophet (sorry Grant)that had "delaminated" right where your knees would hit paddling solo. We cut out all the "bad" stuff and built it back with layers of kelvlar and resin, finishing with fiberglass that could be sanded. West Marine's epoxy was the tie that binds.

I'm with Painter Bob on this one. G-Flex is versatile, flexible, and really tough stuff. However, G-Flex doesn’t reach its initial cure until 7 – 10 hours and it doesn’t reach a full cure until 24 hours. So, having a boat ready to leave the shop in “one hour” might be a little hopeful. Also, there are two types of G-Flex available, 650 and 655 (thickened). Depending on the size of the boat's hull cracks, you might want to go with the 655 (thickened) if they are larger. Here is a link, I'm sure most have seen, to the West Systems G-Flex demo and torture video:

Dryer sheets (things you put in the dryer to do whatever) and a marine adhesive. Or something like that. Clean as usual, and put as few as layers down as possible. If this is a proactive patch it would work without filler if the boat is not used that much. Again, I would defer to Dr. Dale on this method.
That will be $00.02.
