I've inquired with a plater of which does not have experience with bicycles. Quite the process before final dip (as noted above). Chrome plating a fine bicycle frame is a complete different art and requirement vs. random car parts or other artifacts. Obviously you want to minimize bb threads or the inside of the head tube from chrome, but that's secondary issues.
Prep is crucial in anything, flaws underneath will show through. You have to spend the time in perfect prep before the stages of plating.
Old chrome and pitting requires a near complete peel down to the object. I say object because they chrome plate plastics and metals.
No verification but from what I've only researched on chroming bikes, improper plating and thickness of layering can change the tubing property brittleness and ride characteristics.
