Optimal Temperatures

Well it is a nice toasty 46 degree out. Little chilly I think but I was wondering. Given time not being an issue on completing a fiberglass project(my spare tire wheel mold) will this be warm enough to cure over a span of like 6-8 hours or possibly into tomorrow? Obviously I'd use a little bit more than the recommended ratio since it is a bit under the optimal warm temperature, but would that be enough? I don't wanna use too much since that can weaken the strength of the FG. A fast reply would be awesome so I can get at this. Basic weather outlook for this week/next week. I am also wanting to have my system put in by the end of next week.

Temperatures are shooting highs into low/mid 50's for the next 10 days(wow, that right there is impressive.) But late next week I am looking at showers along with t-storm sometime saturday. (I work like all day anyways, but figured it might matter.)

I think you should be fine with that, esp. if you have used a slight bit more mekp, might affect drying time slightly but not too bad, what material is the resin soaking into? Coremat?

If i want something to set quickly i put it in a garage and whack the heat up or use a hairdryer, if you have any pics it might help
