Id like to get some work done on my truck as I have no work or school (college) for a few weeks. I bought the following filler and am uncertain if body filler is like paint, where if used under a certain temperature your asking for trouble down the road. Im working in my garage but it is not heated. Currently working on the front fenders for my 52, which are stored in a fairly warm room off of the garage.
