Fiberglass + Cold weather

add extra hardner for sure, use a hair dryer or if it was me and I was working in my trunk I would put a space heater in there and close it up, if you do that I take no reponsibility if you start a fire though.
You can also use a heat gun but keep it moving it will boil/burn the resin.

All good ideas but one thing to keep in mind. This is a chemical reaction, more hardner means more heat that it produces as it reacts. Don't use too much and keep it away from flammables. I know of one car for sure that burnt due to the use of too much hardner and flammables near by! Just my .02

I recently did some fiberglassing work in -5 to -10 Celsius weather (pretty friggin cold in the Lower Mainland) but adding more catalyst (hardener) only works to a point. Before knowing this, I added a WACK of it to speed up the process. Like 20 ml to 200ml of resin It didn't make it cure like it would if I was working in +15 temperature using a normal amount of catalyst. And it stunk like catalyst afterward too. No matter what, you gotta let it set overnight. Using a hair dryer will help though but going overboard on the catalyst doesn't do what you might think.

i say heated garage / wait till its 20 celcius outside.. seeing as i don't have the heated garage, and the hangar that i do work in isn't heated, other than by propane, i'm thinking i have to wait till February/march to work on my fiberglass projects
