Yep, perfect oven set set up.
If it is that cold the resin might not cure properly if it is summer grade. In winter they add more accelerant to the blend of polyester. More catalyst won't help once it is past a certain point, which is why the heater helps. Check the date on the resin. If it was packed in summer, this is the problem.
You can buy the accelerant to add to the resin before you add the catalyst in winter, but it is a whole lot of mucking about.
And always buy just enough resin to do the job. Buying a 20lt drum and sitting on 18lt over a year is just a waste of money because it won't be the right grade for the time you are using it and a year later is probaly full of water and useless.
Of course getting something in date from a local hardware is going to be difficult, so I always prefer to get it from an industrial material supplier.
All you need to do now is to start vacuum bagging using your compressor with an eductor to create the vacuum! cheers michael
