cold weather wont effect epoxy nor will heat. it doesnt get over 350 degrees anywhere on this planet. most cheap epoxies will hold up to 250-350 degree temp and not yellow and burn up. trust me most cf hoods are made with cheap materials. esp if you get them for less than 800 bux they are garaunteed not to be autoclaved. (baked) so you never know but my experience with adv composites is under 250 degrees the matrix of the resin wont degrade.
