Does anyone here know how to properly refinish wheels from a 1986. I have had my wheels refinished 2 times by a local wheel shop. The wheels where stripped, the surfaces where CNC machined to restore the correct pattern on the face and then clear powdercoated. They never last more than 6 months without hideous white blotches appearing under the finish. These wheels never see the wheather, they are garaged almost all the time. Has anyone had long term success with refinishing this type of wheel. The shop that refinished them said that the 84 to 87 wheels are very porous and that's what causes the problems. Any experiences wheel finishing advice is welcome. How does chrome stand up on these wheels over time? Does it also have problems in time?
