Hi guys, I just tried to do a resin infusion (doing it as a hobby, glassing wings for model aircraft) in the garage and the resin just didn't want to play ball. After 5 hours of using a heat gun to get the resin to flow into all the spaces on the wing (doubly hard to do the top and bottom of the wing at the same time) and the damn stuff just wouldn't shift, what's the minimum working temperature for this stuff. It's been a cold night, started at 4 deg and it went down to -1 deg. I know the pot life is 40-60 mins, I guess I stuck with it out of desperation as the wing alone took 38 hours to shape . Any input would be great, thanks guys.

Hia, thanks for the reply, I fear it's too late to recover the peice, a second inspection with fresh eyes reveals that my exuberance with the heat gun has melted parts of the wing, ruining the airfoil. I think this one goes down in the "lesson learned" book. Good idea about the heated bed blanket, it should just about fit underneath (2 meter wingspan). I think next time I'll do it indoors and not in the garage, at least the process is clean, I hate doing wet layups .

Oh nooo... I had the same issue 3 days ago! wish this post was already up! fortunatly i wasn't doing anything as big as that so I feel your pain. it was just an angled bracket thing but it was seriously slow, the penny never dropped that the cold would change the viscosity that much! plus it took about 2 days for the resin to cure, it's still a bit floppy now! I thought I had a bad batch of resin or was using the laminating one! I might build a warm box with a small heater and some kingspan insulation, one of my freinds did one for when he had done a repair on his jetski, I can see why now!

What does everyone think To the idea of a fan heater in a box about 1m x 1m x1m, I don't really like the idea of anything that could catch fire, but I guess if i leave plenty of space around it and maybe put a desk fan in too to stir it up some more it should be fine, they have thermostats built in so it wouldn't ever get over 30deg anyway. I think it would be cheaper that trying to heat my whole shed!
