So after driving over it a few times, then towing my daughter's car down the street, figured better test that same part for thermal toughness. So off it went into the autoclave. Perfectly fine and now sterile! That is 124C steam under ~2atm of pressure for 30 minutes. Since this part is never getting used didn't wash it first to get the grunge from the tire off you can see at the top. The sharp parts are still sharp and the straight parts are still straight, and it still flexes the same... Love this stuff!
