Refinishing boom ends

[Drinky Crow]

which are castings black anodized I figure but all crusted with white which I figured was salt deposits but didn't really come off after a night in salt away so probably oxidation scrubbing with brass brush lifts it off but reveals brownish substrate of some kind any ideas for liquid solution to clean these up or am I gonna' end up media blasting them and then either powder coat or Tremclad?

I think the best solution would be blasting and powdercoat.

Or, wire brush on a grinder followed by light sanding to create a rough surface, Salt Away, primer, and paint. That means that you can DIY without a big investment.

If most of the anodizing is still good, you might just clean the white corroded spots and spray paint black over the anodizing. Anodizing is far better than anything else you are gonna do including powder coat.
The other option is to blast and just leave it bare.. it's aluminum... it doesn't need to be black.

Yeah I'm leaning DIY here. Spars are white just Tremcladed spreaders gloss black thinking flat black for boom ends would look OEM sharp.
