Hi Ian just having a pair of BMW wheels powder coated at the moment for about £45 the pair.The place is over by east grinstead if you know were that is.I can get you a phone number if you want let me know.
Have had my frame & swinging arm powder coated by Triple-S in Barnsley (or Bingley or Bolton or somewhere equally Southern ). Finish is excellent & turnaround (door to door) within a week. Not cheap tho', £250 all in. Wheels must be cheaper.
My mag Marchesini's are showing signs of "filiform" corrosion under the paint finish..I was thinking of getting them stripped and recoated. I rekon they need a "chemical conversion coating" (Alodine 1200) to etch the surface prior to coating. Can you give me the number of the East Grinstead place and I'll check if they can do Magnesium Alloy wheels. Ta, Richard
