Heat doesn't cure RTV, only exposure to air and time.

Vulcanizing. Heat may open air passages (tunnels) within the RTV, which is why the DoD bans heat application to RTV products. If you are trying to seal up something, why heat it and create tiny tunnels?
Now epoxy, yes - heat that stuff! It shortens the cure time, and makes bubbles trapped within to pop, making for a better cure. But RTV, no.
