because tolerances
The anodising is easily thick enough to push you out of tolerance, and that's assuming you only take off the anodising. Sodium hydroxide dissolves aluminium better than it does aluminium oxide, so you're likely to remove base metal too.

I could of course mask the head tube interface, and inner surface of the cup so to only attack the outer surface of the cups that don't touch anything else than air...?
Grease would theoretically work right?I've developed a working method with caustic soda of using thick drain cleaner fluid so higher viscosity, enhanced by the small pellets of caustic soda leading to even higher viscosity and potency.
Please shoot me down if still stupid. Although you generally don't need encouragement for that..;)

I have a black headset that I want to make silver.
Would you hyve mind recommend against popping them in caustic soda because tolerances of bearings and head tube?
Have had some good and satisfying results with deanodising parts a while ago and still have the kit and drain cleaner.
