Anyone familiar with the Nickel coating process of the slide? Is it just a standard electroless nickel process? Does the tenifer coating remain intact or is it stripped? Does the nickel coating make the slide more durable than its standard coating from the factory? I'm just trying to get an idea of what the process is like. We send parts to electroless nickel from our machine shop. A buddy of mine has an older g22 and the slide is pretty marred. I was wondering if the nickel coating would be a better option than sending it to the factory for refinishing. I also was thinking of doing a barrel or two in electroless nickel.
