Campy magnesium rims must be properly refinished. Stripping and painting alone will not work. Furthermore, power coating is even worse. Suggest you contact Michale Savage. He runs a FaceBook group and here is his recent post:
We are done for 2023 repairing and refinishing wheels. If you are interested in having a set done, we will accept them after Feb 1st. Without Repairs, the cost is $1,200 for a set of 4 at 7/8 ( 10" and GT4 wheels are slightly more). plus shipping back to you.
The color has been laser scanned from a NOS Campagnolo wheel that had never seen the light of day until I opened the box.
The steps involved are:
- Visual Inspection
- Chemical Stripping
3. Washing and Another Inspection
4. Media Blasting
5. Crack Testing
6. Washing
7. Prime
8. Hand sanding
9. Color Application
10. Clear Application if desired.
11. Package and Ship
If at any of the inspections, damage is found, you will be contacted, options are:
a. Stop, it's not worth going on.
b. Find a replacement wheel
c. repair with welding
d. Machine the repair
e. Resume refinishing.
Please contact me by email if you are interested.
