You cannot plate chrome on an inside diameter under a certain dimension. The result is clouded looking chrome. The seat lug and seat stay junction on a frame contains many inside radius that won't chrome properly. One solution is to cover with paint the parts that are clouded chrome plate.
It has something to do with the electricity field that chroming involves. I suggest a search on Google.com if you'd like to know more about the chroming process and its limitations.
