Hi, Guys. I've reached a bit of a standstill on my 76 project, I dropped the trans off for a rebuild and it'll be a while before I have it back. In the meantime there's some fiberglass repair I could stay busy with. I live in Massachusetts where we have real winter, it's been pretty cold here. I can maintain 55-60 degrees in my shop, is that warm enough to do fiberglass work? I don't want to waste time and material if it's not going to work.
Thanks,
Peter
Thanks for the replies, everybody. Looks like I'll wait until spring, I don't want to push my luck and limited fiberglass skills only to have a bad repair fail.
Thanks again
Peter
Remember fiberglass and body filler all cure to the warmest temp it gets, not a big deal if you say you can get it hot but it won’t fully cure until it gets to its most extreme temp. Like bake booth temp 160-165. If you let it sit in primer through the summer before you paint it and park that sucker in the sun every once in while you will be fine, Just don’t expect to paint over it any time soon and get a lasting quality job.

60f min is completely fine..good luck! Mix well and keep raw materials in a warm place prior to use

I. Just discovered similar rules apply when recovering fiberglass panels with upholstery glue....the leather-vinyl has to be preessed down onto the panel until it finally decides to adhere
i have a little torpedo-jet engine heater. works great. sometimes with bondo (65-70 mustangs when they were 300 bucks) i would mix a big batch and leave it in the cold. spread the filler and point the heater. 5 min later it could be rough worked and use more of the same batch i mixed and left cold. with smaller repairs a heat gun or hair dryer will work the same. harden quite quickly enough to lay up another layer.

I did some last winter in a fairly warm garage and it took a while for it to dry, it hardened but was tacky for a day or so. I would wait like you said. It really isnt worth the risk
Fiberglass Temperature?
