Rich you are talking about the rubber separating from the pallet correct? not the actual honeycomb pallet coming apart? I was thinking the pallet because of the heat they would retain, but just wanted to make sure I understood what you were saying.

The glue that holds the honeycomb pallet together will soften over time when you apply rubber as the rubber will retain the heat more so than the aluminum. I have replaced a few thousand under warranty and will no longer build them. If they work for others great.
