Floor Storage Support Flange

I want to "paint" or otherwise restore the support flange for my floor storage. Obviously a high traffic area and sometimes a cooler may get drug across it. I assume a rattle can ain't gonna cut it. Appears to be aluminum. What would you guys do?

First, take it in to either a paint supplier or bodyshop and ask them to try to match some urethane single stage.

Then sand it all down, clean it, spray sealer, and paint.
