Bought for first use for gluing smaller rubber feet onto cast iron oven grates. Easy to use as it is gel rather than thin super glue. The glue didn't last more than a week on me. There was some peripheral heat conduction from the grate, but not much heat since the corners of the grate were located on the stainless steel oven frame away from the gas flame. Personally I have not had much luck with any superglue for glass repair or applications other than finger bonding, I recommend using cheap disposable gloves like those used in hospitals when working with these glues.
