[QUOTE="Buzzdraw, post: 2974154, member: 385"] Just a couple technical details. Hard chrome can be applied to carbon or stainless steel, not aluminum. HC typically goes on 2-3/10,000 and runs Rockwell C70. It's quite durable. Can't do springs or aluminum triggers. I've found it to work best when applied as the initial finish. It's appearance mirrors the metal finish beneath it. It is rust resistant but not rust proof. HC is my favorite for cost effective hard use durability of steel guns. Electroless nickel is pretty good, going on for a RC of about 50. A little more rust resistant than HC. Stripping EN off an existing gun takes a nasty toxic chemical bath. Aluminum can be re-anodized some of the time, depending on the base aluminum. There are a couple types of aluminum; in terms spec decorative and mil-spec. If the aluminum is of the wrong spec for the process used things can go bad. Cerakoting is reasonably durable and comes in lots of colors. Other more exotic coatings out there including boron nitride, boron carbide and others. [/QUOTE]
