Mobil 1 will burn into the metal like most synthetics and will turn metal black and you can't get it out.. I'm not sure about frog lube or Seal 1... I use the two but only on lock works and slide and lube points that can't get supper hot.. Some chambers can get hot enough to cook off rounds in the chamber.. I'm still old school but slowly working on or with some of the new products out there..George
