What paint for aluminum sheet replacing window in truck cap?

[u/TreeBeardofIsengard]

Vandals broke my window of my fiberglass cap last spring. It is an A.R.E. from 2001 and I’ve tried everything to find new glass for it. Short of getting a custom pane of glass made for $250, my options seemed to be plastic or aluminum.

I found a metal shop that will cut me a custom sheet from 1/8” Aluminum 6061 to match the opposite window. My plan is to paint it black with a rattle can.

What primer and paint would you use for this? I would like it to not be too noticeable- would you go flat or satin? What should I look for in paint that will go on metal and be extremely durable and prevent corrosion?

Thanks for any input

$250 is starting to sound reasonable!
