Need some help with a coating to protect the iron of a BLDC stator and PCB boards. I've been getting issues with small BLDC motors with rust and electrical issues (open/shorts) on the stator and PCB hall sensors that are caused by autoclaving the motor. The motor is placed in 10 minute autoclave steam cycles (134°C). Things I have tried are nail polish, silicone based conformal coating, and high temp petroleum jelly. They all work a bit just want something better. Potting 2 part epoxy re-sin will work but I like something that I can brush on the stator and PCB components in room temperature.
