There are safer ways of determining if a part is metal or not. Seriously.

It is aluminum, brushed and lacquer coated.
To paint it lightly scuff it with fine steel wool, clean and spray.

Not likely... but ok.

Might work to take it off with steel wool, might not.
Try it on the back panel or someplace not visible, I guess...

belt sander is a sure bet...??

Otoh, somehow I doubt that black paint on the front panel will effect the dynamic range, subtly or not. Wait... it might... nah.

I've painted over bare aluminum with spray lacquer before (DEFT). It's been over 3 year now and it looks exactly the same as the day I did it.

I have a DCX2496, do you? It is a brushed aluminum finish with a thin coat of clear lacquer to stop oxidization. Understand?
The purpose of the steel wool is not to take the lacquer off, it's to prep it for a new coat of paint. Anyone who knows anything about doing this would recognize what I am saying.

Belt sander...
Best to say nothing if the advice you bring is not only useless but also harmful.

Anonymous,

I'm interested in possibly painting plain (non-anodized) aluminum ..but only if it's low effort!

My biggest concern is flaking of paint where other metal parts (screws, transformers, etc) come into heavy force contact with the lacquer and the eventual separation of the lacquer from the aluminum. From your pic it appears that you only have non-metal parts in contact with the surface. I guess just try and see but any thoughts?

I can't seem to source DEFT (or any other brand name) spray can black lacquer online. Can anyone point me in the right direction?

Honestly, I think any non-anodized coating will run the risk of chipping anywhere there is forceful contact with another metallic object.

The front of that same chassis in the pic is also painted aluminum. I used self-etching primer and then regular spray paint over it. It has held up perfectly fine, no flaking or anything. It isn't bullet proof though; it can definitely chip if mistreated (especially the sharp edges).
