[Repeater-Builder] Painting

[David]

So I have been trying to put together and rebuild a bunch of equipment 
for the hilltops. Just got another set of Moto T1504 UHF cans. I have 
been attempting to do a neat and tidey job (for a change) and make sure 
everything is clean, and wired neat and such. 
So now, the inside of the duplexers are redone, What kind of paint 
shoud-could-would I use to paint the outside to not effect the 
performance?
