Finished!
The amp sounds wonderful. Clean, and no hum or noise whatsoever.
I painted after making drills, but before mounting components.
After several weeks, the paint is still in place. There're a few little scrathches, probably made while mounting things and working on the soldering, exposing a very tiny area (less than 1 mm size) of aluminium (or primer). It could be painted again with a fine brush.
Definitely not perfect. It has to be treated with some care. But the paint procedure I used seems like a reasonable alternative to more complex or expensive ones.

My next project is going to be using a steel chassis, though. Never worked neither painted steel before. I expect a much harder to work material (drilling is not of concern to me, but cutting definitely is) and easier to paint.

Yes, compared to Aluminum, steel will be a bitch to fabricate by hand. Any commercial powder coaters nearby? For either material, I've found the extra few bucks over the raw cost of material for aerosol paint products is easily justified by the reduced prep time, and durability of finish. The local shop I use pre-washes to remove any residues that could impede adhesion, and they have a great range of stock colors and textures.
