Hi Joe, I can't comment specifically on the epoxy you saw in the magazine because you don't have the manufacturer, however all the epoxies I have read about that are designed for use in cooler weather simply have the feature that they will harden at cooler temperatures - they will still harden faster at higher temperatures. I doubt that the article said that the epoxy would cure faster in cold weather than warm - likely it simple pointed out that it WOULD cure in cool weather. But if I am wrong (it happened once before in 1962), please provide specifics so that I can expand my knowledge. Here's a link to System Three Cold Cure epoxy: http://www.systemthree.com/reslibrary/tds/Cold-Cure_TDS.pdf It states that it will cure down to 35 degrees F - doesn't say anything about curing slower at higher temps. Thanks.
