Not sure of the Fusion as I only have used it on Electric planes. The OLD, "normal" stuff I used on my Kougar certainly was. The exhaust pointed right on part of the painted parts. And after a good 10 years or so of a lot of flying, the paint was about the only thing intact when it crashed. (Broken elevator push rod in a dive... wasn't pretty ) Can't say if the "new and improved" stuff is.
As with any new process, best to run a small test.
