I want to fiberglass my trunk but wondering is the cold weather going to cause problems?

Well i just want the first layer to dry so i can get an initial fit..

Then i will work in the basement of my house to keep it warmer and apply layers and layers..

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

 

Lots of hardener will make the FG much too brittle.

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
