Hi, anybody know what the finish is on these acs hubs - the finish is original. I bought them on museum thinking they were anodised, but the finish is 'on top/over' and not like anodised 'in' the aluminium. The finish looks like a gold plastic film over the top. The hub bodies are in great condition and I'm looking to finish them after stripping em back to raw.

Coloured lacquer is used on ACS and SR hubs rather than anodising, same as Shimano pedals and the like.

You got to use paint stripper too remove the finish.
Just stripped a red set with this stuff I purchased .
Tried nitro mors paint remover and to be honest it is shite..
This stuff below did the job.

I like the hubs & am slowly restoring a pair of 1979/'80 sealed bearing types. But Ady is right, the cheap arse painted finish, is crap. Just one scratch or paint chip that exposed the alloy underneath would lead to corrosion which worked its way under the paint leading to more paint falling off.
Painting them meant that they did not need to fully machine each hub & many will be seen as essentially been pulled from the casting mould with the mould join mark still evident.
ACS advertised this finish as being better than anodising. ................ They lied.
