Rust protection idea

I’ve got rusty hands. You can literally see my rusty handprints all over the shop. It drives me crazy.

I’ve been searching for solutions and am wondering if anyone has tried using “conformal coatings” which are aerosol sprays commonly used in the electronics world to protect PCBs from moisture?

I’ll get hold of some and give it a go but in the meantime has anyone else tried this to protect their tooling?
