The hardest thing about this post is figuring out in which forum to put it!

I have found the treble horns of my (affordable) dreams: the 2" throat Emilar EH500-2.
I have managed to acquire a pair of them, but both of the ones that are now mine (bwahahahahah! mine, all mine!! ;)) are suffereing from pretty serious loss of paint.

The horns are cast aluminum & appear to have been unprimed. The satin black pain that's on them is not well adhered.

My question: is there a straightforward DIY way to repaint them (or touch them up).
They don't have to be perfect but it would be nice if they were all black.

The "phase 2" question is: is there a reasonably cost-effective but really "proper" way to have them refinished? I am guessing sandblasting or bead blasting or suchlike would be part of the process(?).

Thanks for any and all suggestions.

PS: FWIW, this is what a "picture perfect", pretty EH500-2 looks like :)
