Default Finishing ASC capacitors

I received the ASC capacitors for my upcoming build and I have a question: has anyone left them unfinished? Do they oxidize without a clear coat? How about a simple metal polish? Recs welcome.

Aluminum oxidizes immediately upon exposure to the atmosphere. It's quite lucky that this micro-layer of aluminum oxide is crystal clear.

Yes, they do. Best to sand them slightly and paint them with an aerosol paint of your choice. Easy to do and they look superb.
Cheers
Ale

What about a heavy polish and clear coat? I'm liking the idea of bright polished metal.

Here is the method I have used with great success:
  1. Remove label and residual adhesive
  2. Hand sand with non-woven sanding pad - Maroon (00), then Gray (000), then White (0000)
  3. Spray paint from can. I use Rust-Oleum Mist Metallic Spray Paint, Carbon Mist 261413; Generally one coat is sufficient.
  4. After several days or a few weeks, use a light clear wax to protect (apply by hand and buff). I use Briwax for all wood or metal finishing.
Have Fun!!

You could also polish them with some mag wheel polish, they will stay shiny for a long time and are easily repolished if they get dull.

If you want to use paint, clean thoroughly and apply a good, self etching, automotive primer, before the top coat(s) go on.

That's what I did (Gord's Aluminum Polish). It's possible to almost get it to a chrome-like shine. After six years it looks the same.
