[Paddlewise] Need advice on how to repair a slit about a foot long in an 18' coleman canoe

Not sure if this the right place for this, but I'm trying anyways.
Neighbor up the street was selling his 18' coleman canoe for $100. It's not
in too bad of shape, some deep scratches/gouges on the bottom, and it had a
patch on the inside. Went to pay him and pick it up today, and I noticed the
patch was starting to come off of the bottom of the canoe. So very gently
with a single finger the patch pulled off quite easily, and I mean easily. I
showed him the patch pulled off. The glue underneath was hard and brittle. I
talked him down to $80 for the canoe, so now I need to know the best way to
repair it. I've repaired my fiberglass canoe before, I still have it. Just
no idea how to repair this tupperware stuff coleman uses. There's a Coleman
outlet store in town I'm planning to check out this weekend. Any ideas let
me know.

Thanx John
