    I need to do some glass work before my arjay goes bad and it looks like it will be really cold when I am going to try to do it.

    PEroxides only work above 15 degrees C (is that some 60F?). 12C, if you stretch the limits.

    Any lower, and no matter how much cobalt you use, you will get an undercured result.

    you can use Basic No Blush marine epoxy with winter curing agent down to about 35 degrees - used to build boats in unheated barns in New England during the winter

    I was hoping to use my polyester resin I already have.
