Fiberglassing in cold weather

[DarthBatman]

Hey guys, It's about 50 degrees here in Oregon and I wanted to work on project before Portland ComicCon. I was wondering if the fiberglass resin will cure correctly in this weather.

well my can of 3M Bondo fiberglass resin says use above 45 degrees, and cured well for me a couple days ago at 55. check the small print on the back of your resin can and it might give you its lowest curing temp.

hope this helps

You can always use a box and a heatgun/ blow dryer / space heater to create your own curing oven. Just be sure to have enough distance from the heating element and the box and item to be cured so it doesn't start a fire, and don't have the heat too high or the parts closest to the heat will cure faster and might warp the over all shape.

If you can't warm up your work area, at least get your parts (and DEFINITELY your resin) to room temperature or a little above, and then take them out and resin immediately. I've never had a problem with drying or adhesion doing this at 50 degrees, but I only did it when I had to (on vehicles when there's no room to pull it into the shop :lol)

***totally agree with CJGrimm, a heated room is great, but using heat directed on the area can cause warping and also cause the resin to cure poorly***
