No, nothing saved on this. I just picked up some of the high-temp sealant from the auto/RV section of a local variety store after reading about it somewhere, scuffed up the area a bit, and smeared on some of the goop where I thought my fingers and mouth would hit, then let it cure.
I have applied the stuff to 12 fl oz Vienna sausage cans and beer cans. If the flames over which I cook get too high, the pads get hot, so be aware. How much to use was a guess, but AFIK, one could build up additional layers, as needed.
I did not expect this to get a lot of "press." If you search the board, it will probably come up in past discussions.
