Who here is innovative? - Need to repair a polyethylene hull
Have a hull... call it a dinghy if you will.. made of polyethylene (basically, the same stuff as kayaks)... it's 10 feet long and about 4 feet wide... it was left on shore with waves crashing and terribly neglected. As a result, the bottom of the hull on one side of the keel is deformed... kind of pushed in and collapsed and wavy...
how can i get these waves out of a plastic hull? picture those polyethylene plastic kayaks.... and imagine one whose bottom is pushed in say in about 2 or 3 spots...
there's an inner hull and an outerhull.. so getting in between the hulls to push out on the outer layer and apply heat to reform it is kind of impossible?
what ideas can you come up with?

the hull is kinda "flexible" as you can imagine... designed to sustain abuse i guess, kind of like a rubbermaid boat meant to be abused, except this one crossed the line.
It's crossed my mind to basically go over the entire hull with fiberglass cloth and resin and turn it into a hard bottomed hull... however i'm not sure if it would still flex or not and just crack on me, or if it's even possible to fiberglass over a rubbery palstic hull.

maybe try to heat the plastic with a heat gun and douse it with ice water on a rag to get it to pop back?

maybe a dent puller but then you would have to fill the holes with something...

Can you pop a hole in the inner liner and add pressure say from air nozzle? then heat with the heat gun along the wavy spots.
