Stripping and painting Marchesini magnesium rims?

[Dodgy]

Hi

I have a set of Marchesini Magnesium rims for my road R1. When I purchased them off Ebay, the auction was for aluminium, but now that they are here, I am pretty sure they are mag - no DOT stamp on them

Anyway, I want to strip and paint them. Originally they are powdercoated, but I cannot acid bath them as the acid will eat at the magnesium.

Does anyone know who to go to in order to get this done, maybe even the importer (who are they?) to find out the deal

cheers

Yeah dodgy is about right.
Don't put racing wheels on your road bike ya plonka.

I had a friend back in the day* who had a ducati which had Magnesium wheels on it: He was advised to get them magnafluxed or crack tested because they are not apparently as durable as aloominum. He did, there were cracks and he had to replace them. Just passing that on FWIW, if anything. I am interested in how you get on.

would have thought a fine sand blast might work

Yup.
Racing rims arn't designed for riding over shitty road surfaces and pot holes. They are designed for a near perfectly smooth race track surface. If you use them on the road they will snap one day.
Sell them if you don't have a race bike to put them on and buy some road rims. You can still buy nice lightwieght rims for street use.

Magnesium suffers from inter-granular corrosion when exposed to the elements.This is why it must have a good,intact protective coating at all times.
