I think it will work just fine assuming that your deck is not soft and that you don't fall or jump around close to the handle.

It's funny, once I opened up the board I could feel the total loss of rigidity in the deck.  But after the install, once cured, the deck was back to normal. 

Bill your comment about the relative flexibility is well received.

Personally I would not recommend this in such a high traffic area. The bond between epoxy and plastic is never great and the handle is only offering support through the bonding of its self to the epoxy and in a short space of time I think you will find the deck will move enough to break the bond under the lip and then leak. I would keep a very close eye on it or re install it. I have seen leaks around bonds to plastic too many times.

That's why I would just use Gorilla glue. The epoxy will get harder over time and be more likely to fracture. Polyurethane stays slightly flexible and expands to fill all the voids. It would give a good bond between the EPS and the handle plastic that would be strong and largely waterproof even without the flange. With that 1/2" flange you have a lot of grip. You could also use JB Weld Plastic weld for a better bond on the flange, but it doesn't foam and expand like Gorilla Glue does, so it wouldn't give the void filling bond to the eps.

I would use gorilla glue for installing the handle in a conventional way if the routed hole was a poor fit as like you say it expands and also penetrates the foam however if its only a small gap epoxy and micro balloons is a lot easier as you can just wipe of any over flow. Personally I would not trust gorilla glue to be water tight on its own as when it expands it makes lots of bubbles which can often create voids as it blows out. You would also want to key up the handle very well before using it as gorilla glue or any glue or resin will crack right off that shiny surface, but like you say it will depend on the flexibility of the glue.

Generally leaks happen around were you have something hard  meeting something soft on a board. fin boxes, foot straps inserts, air vents , leash plugs, drain holes ect ect. I see this sort of thing happen all the time working doing board repair, I had one that had a leaking foot strap insert on a windsurf board and due to the constant movement of the deck due to the riders weight it had basically sucked a huge amount of water in and completely broken down the foam under the standing area . The board now hangs on the wall as a demonstration to customers to show what can happen when you get a leak.

It maybe worth doing a water/dishsoap test and putting the board in the sun to cheque that you have a perfect seal at the moment and then regular after every use of so as you wont be able to see easily when it does start leaking.

I'm glad you have done it and shared and very interested to hear how it lasts as a experiment but I really wouldn't recommend anyone to install one like this, its just asking for trouble.

I'm banking on the simple premise that a 1/2 inch FLP (lap joint) will outperform a butt joint.  And you brought up a good point SU, I did key both surfaces with 80 grit, and there was naturally a good contour match.

But again, thanks for the constructive feedback all.
