FWIW:
In selling a process in competition to Zn arc spray, one of
my key advantages was not experiencing flakes of metal in the enclosure.
The arc spray materials are prone to flaking off after aging, thermal
excursions, and flexing. Should not be a big issue on an aircraft
providing all your terminations are well booted etc.

Those that do flame-spraying of plastics, as in creating a
shielded enclosure, can flame-spray the inside of a cowling with a metallic
coating that has a very good reflection coefficient at IR. I had a shop in Paso
Robles do a small test area for me!
