My experience has been mainly the backglass has issues. I had a Firepower a couple yrs ago and sold it to the guy down the street. He had it in his garage that was insulated but not heated except for the weekends while they were out there. The backglass was pretty good but after the first yr being out in the garage, I went to do some board work on it the following spring and when i lifted the backglass and grabbed the sides, the silkscreen just flacked off in my hands. I felt horrible. To be fair I did warn him that its best to try to keep them warm. We did the best we could to salvage what was there and then cleared the rest to prevent further damage.
