Anything that prevents metal on metal contact will work. The more durable it is the less often you have to apply it. Synthetics can have a higher film strength than mineral based products. If you mess around with stuff like this on a regular basis, buy a gallon of eez-ox and a refillable aerosol can. Your guns will thank you.
