Brake master Cylinder painting

Oddjob:
Funnily enough it was about tank badges that I was asking him, he was pretty confident that they’d not last the process and as they ain’t exactly cheap I didn’t feel the need to test the theory. I’ve just sanded a tank badge right down to bare metal and to me it looked like a layer of some sort, like a layer of paint. He did say there were some finishes that looked like anodising but were actually a sort of paint finish but that he didn’t do them.

Going again in 2 weeks so I can ask him to tell me the process again as I’ve forgotten what he said it was called.

In the Tamiya paint range there is a pigment for painting the inside of clear lenses that is gold, silver, yellow, orange etc. I have some gold in the shed and I'll dig it out to have a look. Obvs its in an area wher petrol is about so maybe fuel proof laquer over the top?

If you were to spray it on first as a primary coat with a modlers spray gun to get the delivery and then laquer the lot afterwards once you've done the letters as required, it would  technically be sealed but you'd have the polished metal underneath with a gold finish from the pigment coat under the laquer?

I'll report back when I've found it.........

Sesman:
Thanks for the feedback. Sounds like painting will be the default solution as I can’t afford to be experimental with the anodising risk.

Lobo:
I recently had CB750 Master powder coated - can’t say price as part of a job lot. Very happy though with the result.

Really liking Oddjob’s Clutch master …

K2-K6:
The original definitely look anodised to me, and it will fade over time.

There's consideration as I understand it, anodised components are usually sized/toleranced in manufacturing to give finished size after treatment as it can change critical dimensions. Likely the bore and internal was masked during original manufacture to avoid this, else it has to be anodised then bored afterwards.

More recently in seeing good quality aluminium (known std in cycle downhill frame) the bearing bores were increaesd and attributed to pre treatment in metal removal prior to final process. The bearings had to be fully located in building afterwards by use of strong bearing fit adhesive.  Not so much, but it was there and likely outside what a mc bore would take.
