I have the coverite thermometer and tried 175*, 200*, and 250* degrees, but it doesn't stick at any of these temperatures, same story with the ultracote plus. I used to swear by ultracote, but now I'm going out to find a roll of monocote, and I bet that works.
I have seen a couple of recent posts on the Coverite iron stating it suddenly stopped heating properly. Did you set the temps by the dial on the iron, or do you have a thermometer?
