I will coat the outer surface with release agent, of some description, I assume that this will be able to be removed afterwards and the clamps wouldn't stick to the outer part of the board
The amount of hardener used is very small, the resin is fairly thin (do not confuse styrene resin with gelcoat which is thicker) you only need 3 or 4 drops per 7oz cup, increasing hardener reduces curing time and a slightly weaker and less flexible joint, the higher the temperature also decreases curing time, at this time of year do your injecting and clamping a shed or garage then take into the warm about 20-22 deg. I would suggest your problem is caused by the resin being semi cured when the 2 halves of the board were joined in the mould, not unusual if made by hand in a hot country. my PC is slightly to the right of Genghis

thanks
I have had a look at some glues in my local hardwear store, they had some Unibond 100% power Glue, which is solvent free (no mixing either) and that says it sticks Plastics and Glass fibre is listed, its waterproof and also transparent, it seems to tick all the boxes
The knee-boards will be production line, built by hand, pressed by machine out in Taiwan.
Unfortunately the company i bought it off, didn't pack it very well, for the courier to drop it and split the fibreglass apart. I got a great price, with it been an ex display board in A1 condition, but the end of the season meant they didn't have another to replace it with, instead they swapped it for a brand new 2016 board, not even released over here yet  and i suggested a deal on this one and will attempt to repair it
Either way, I got a new kneeboard, for less than half price and this one for a fraction of the cost it would have been, so i am quite well in front, and i might sell the 2016 board if this repair goes well and make money  Former Mod/Member, with the most post & Chicken George Arch nemesis
