Its also much more forgiving on the thumbs! 😂

As temps are down to single digits here and the tape is a bit firmer to handle, they're still usually throbbing by the time I'm through!

Yeh in winter I like to put the bagging tape in my oven at 40 for a bit to soften it up again. Or if the whole mould can fit in then I'll put it in the oven for a couple of hours after bagging it to both soften the tape and warm the mould surface to improve resin flow.

It currently the opposite here at the moment though, 40+ degree days mean the bagging tape is super soft and hard to get off the roll cleanly. Just can't win!
