If chrome is de-laminating from base metal- there are 2 choices: strip them down and get them replated, or, have base alloy polished- RGX did an awesome job on mine (they were curb rashed,badly...) stripping/painting is an option as well- re-chroming is REALLY expensive....
RGX should be able to help you with this problem, but please call first to ensure that they can fix the problem.
