+xAlmost certainly; you could put it somewhere warmer or just wait a little longer. As a very rough rule of thumb, a 10'C increase in temperature halves the associated curing times and so a 10'C drop in temperature will double the curing times. Ideally you would maintain at least 20'C for the full curing cycle of the resin but in an unheated workshop/garage at this time of year, it could easily drop well below that. I'd leave it for another 12-24hours before demoulding but see no reason as to why it should have failed, it just needs more time.
It come out quite well.Think to fast infiusion create small air pockets.But the temp. Was the main.issue.I know now if resin is cured in tube it should be fine.👍
