Abstract
A cutting tool having a hard tip is pressed with a uniform pressure against a surface of a vehicle wheel as the wheel is rotated to smooth and seal the surface. The smoothed and sealed wheel surface is then chrome plated with a process that includes applying a nickel layer directly upon smoothed and sealed wheel surface and a chromium layer over the nickel layer.
