Chroming is a crazy thing. You figure, you send your parts and first they have to be stripped. Then before anything, your parts have to be polished. Then in case of heavy pitting, your parts have to be copper or brass plated several times and made to be polished to a mirror finished. The chroming will only be as good as the initial surface of the material to be chromed and that is why it can take alot of prepwork before your part even hits the nickel plating tank. Then the parts are chromed plated and sometimes triple chrome plated. The chrome plating gives your nickel the depth and durability of shine. If you see the chrome tank, it's a rootbeer color, for lack of a better description. Then it really depends on the type of chrome plating. Hexavalant is one type and their are 1 or 2 others that escape me right now. Depending on how labor intensive the part preparation prior to plating is, determines the final cost. It's highly labor intensive. Also environmental factors have done alot to drive up the cost of chroming and drive away many of the small chroming businesses that existed at one time. There are chrome companies that have worldwide reputations, but they cost but can do amazing things with some really horrendous parts. If you have an original part that is basically no longer in existence, then oftentimes you may not have a choice. But we are talking trikes here, not bugattis, so it can be hard to keep things in perspective.
