Spray finish on window screen frames?

[Greg1410]

I stripped and cleaned up the window frame screens and polished them up to a nice shine. Debating whether to put a clear coat on them for less maintenance. Any advice do this? Advice?
Thanks,
Greg

I do some art from aluminum & have clear coated it. If you get the wrong kind it will yellow in time. I learned this the hard way.
It was rattle can clear coat.
