Now that Winter seems to be finished in the Midwest I'm debating if I need to remove my thermal blanket. GMG recommends removing after a certain temp, but what would be the harm in leaving it on year round? I know I should look under to make sure there aren't any rust spots or anything, but aside from that, I'm in IA so it can get 90s in the Summer. Is there any risk to keeping it year round aside from maybe not being able to maintain a 150 when its hot?
