Quick repair question: Epoxy related

Had a snowboard tip and freefall whap the concrete causing a tiny edge deform and small delam. No big deal for a fix but I went all rabbit hole on what epoxy to use for repairs due to it needing to remain somewhat flexible. I've read reference to wanting lower numbers on the Shore D Hardness scale, but many epoxies are in the 80 range with little real variable.

I've looked at  the following and think any of these will do but they're really expensive:

WEST SYSTEM G/Flex
Devcon 2 ton
Araldite 2011
3M Scotch-Weld DP190

So my question is (if anyone knows):  Why not use an epoxy resin that they use in the construction of new boards? I'm looking at ReBoard Epoxy or even Bulk Marine Grade. Are those even different things? There's a lot of options out right now because of the river table trend.

Of course I don't need that much to buy bulk, but it's more of a question to see if anyone here has gooder insight and knowledge.

Because that is a heat/pressure cure epoxy.

G-flex is what you want, and it’s what almost all techs use for  

Get the area as clean as possible, use rubbing alcohol. Then you’ll want to use a heat gun and toothpicks to make sure you get the epoxy as deep as possible into the effected area. The heat gun makes any trapped air bubbles rise to the surface. ( air bubbles will make the epoxy break down ) then when you're sure you’ve got it, wipe it clean, put clear packing tape on the base and topsheet of the repair area then clamp with a plastic scraper on each side. 

That’s the basics of it. The 3 most important things are it being clean, no air bubbles and a jagged surface for the epoxy to cling to.

Sometimes people try to make a repair area all perfectly clean/ smooth by cutting away material, and that’s a mistake. The more bumps/jagged edges, the better your g-flex will hold.

Ah. I knew about heated presses and wasn't putting it together that it was for the epoxy cure. Thanks for putting that together for me.

Got my Yes Optimistic in the shop the fix up the bunged nose. While looking it over I noticed I had a delam on the opposite side of the board about 7-8 inches long right in the middle. There were no visual signs of any impacts or base damage. This coupled with the fact that the nose delammmmed from a single tipping fall makes me wonder if this board wasn't made on a Friday. Seems maybe they went light on the epoxy on this one. Now I've definitely put some runs on the thing but I've never had a board delam without significant damages. But whatever, should be good to go.
