I have never heard of one that is more reliable.
You might consider an alkaline electroless nickel strike or a nickel sulfamate strike before the chrome. Caution, it passivates rapidly. The biggest problem with this is the rack has to have ALL of the chrome solution/stains removed or it will gradually kill the strike tank.
