Flitz is a company that makes a series of excellent waxes and polishes. Some can be used as a steel polish and an aluminum polish, others can be used as a general metal polish. They even have products to be used as a car polish. We use Flitz products in the shop on our air rifles and air pistols to clean and polish barrels and wood stocks. There are few polishing products more versatile than Flitz products. Give them a try and you'll be happy with the results.
