Modular Synth Panels

A question for those of you who screen your own panels ...

I have some 5052 grade 0.125" thick aluminum cut to size that I'm  
going to be using for panels.  Should I get this anodized to the  
proper color, or is it suitable to paint before screening?  what  
sorts of paint/ink should I use to paint/screen if this is acceptable?

just curious to see what the common consensus is ... clearly anodized  
is "nicer" but also more work & more expensive ... wondering if it's  
worth the effort.
