4 layers of 450gsm, and whatever tooling resin Nord produce. I’ve almost finished now, but calculate I need about 3kg more resin than I have, so have stopped. It was a bummer because I had enough time to get totally done. Better order another 25kg
It has a much lower styrene content than laminating resin as well, which is nice. I catalysed it at 1% and that was enough. For mixing 1kg the brush was just starting to drag as the pot was finishing.
I expected a harsher exotherm though. But puzzled at that. I will post cure the mould though.
