3932472 Aluminum Manifold Care?

I have a factory aluminum manifold on my 69. It looks great after it has been bead blasted. Can anyone give me advice on how to keep it looking that way without spray paint?
Thanks

What's the aversion to paint? A light dusting of cast blast silver will fill the open pores the bead blasting created, it will look closer to a factory finish and spills will wipe right off.

I have had good luck using Never Dull wadding on alternators and other less porous parts but fresh bead blasted cast parts just want to soak up dust, grease and fluids...

Is powdercoating a good option here?

If it was blasted at low psi, follow it up with a good rubdown of steel wool. Clean up will be a snap, just a quick wipe with a wax/grease/silicone remover.

I think the problem with blasting is when done at high psi, but have never done one that way. Ive done a handful or so the last few years and staining, discoloration, difficult clean up, etc. is a non-issue. And that's not even cleaning up right away as I've gone back after months of heat cycles and still no problem.

I use plasti-kote brand clear 500 deg. with great results. Looks great for years.

I guess I forgot what the manifolds looked like when they were factory new. I assumed the fresh beadblast look was the same. Do you think a clear paint or the cast blast would be a more original look?
Thanks
