Wow, I never even heard of it before this.
They offer electroless nickel plating for cheaper, what's the difference between the electroless and the metalife? Is the metalife more like the "Nickel Boron" coating from WMDGuns and NiB-X?
I have a 1911 Commander I built years ago. I had the frame electroless nickel plated and nearly 35 years later it is blemish free. It was a Ranger aluminum frame and I'm still happy with my choice.
Be careful I have recently had some work done by his company and it has not turned out so well I sent back a couple of pistols already because of problems with the finish bubbling and chipping.
