Specifically regarding gears and moving parts within airsoft guns (GBB & AEG): What kind of lubricants should I be using? I don't think I need to go out and pay 10 bucks for a little bottle of "Airsoft" lube, so what's a good substitute that I can get locally at like a Home Depot that will keep gun internals running smoothly?
I don't need to know about silicon spray, but if you have any good references list them.
