Dave is this suitable for parts that get hot? e.g. caliper adaptors - if they heat up would the RPM reliquify and drip off??



I used it on my disc brake calipers as well as the head-pipe on the Valiant. It can't drip off because it is applied as a thin film. Even if you tried to apply too much material, the excess would flow and run off of the part. It might turn shiny again if it is exposed to constant heat but it will go back to its normal (inconspicuous) appearance once the part cools off again. It was not developed for components exposed to constant (direct) heat such as exhaust manifolds. Those type of areas have never been tested. It does work well on bolts and pieces located in the engine compartment.
