Repair the keel of a polyethylene kayak

I’m looking for someone in Southeastern Pennsylvania, USA, who can repair a hole in the stern keel of my Pungo 120 kayak. I’d try the melted polyethylene technique but I’d rather go to someone who knows what they are doing.

Yes I’ve been in contact with them and they sound great. But they a bit far from me. If I can’t find someone nearer I’ll go to them.

You might contact the Philadelphia Canoe Club to check and see if any member there is practiced in thermal welding of polyethylene boats. There is also the Lehigh Valley Canoe Club.
