Paul1977:
But in seriousness... most gas grills will have flame tamers, so would it still be too hot?
I'm working on that basis as have been using these things over the grill but you can't directly see/touch the flames because of said flame tamers... The sheet's not showing any sign of charring or melting... but the current one is starting to lose it's sheen and now I have to wipe the muck off instead of just rinsing it.
