For aluminum, I just put 320 grit sandpaper on my electric vibrator (not *THAT* kind of vibrator...) and it leaves a nice swirly pattern. It's very easy to find surface imperfections by the blurry ring around them, so just sand that area a bit more.
I dont leave bare metal exposed on frontal areas; they get painted then I apply laser-printer decals. A co-worker had a panel made thru frontpanelexpress.com, and he had it powder-coated. It was beyond awesome. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
