I was wondering if anyone has any advice on how to replicate or clean cast parts back to a freshly cast look ? Specifically for suspension parts that were not painted from factory.
Iam not really interested in painting it, I would much rather just get it cleaned somehow and satin clear it to maintain the OE appearance.

Any ideas besides sanblasting ?

I know that you said that you don't want to paint them, but the cast iron paint by Bill Hirsch keeps that cast iron look without rusting. Once it is painted, no one could tell the difference between the cast part that was blasted and the painted part without rust on it.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

Any exposed metal (steel or iron) will react to moisture in the atmosphere and rust. The only way to prevent it is to apply a coating. I agree with the cast paint which looks like natural but does give the coating.

Appreciate your response, I was thinking if there was a process to restore the cast metal back to new that i would then satin clear coat the cast part to stop any further rust.

May have to resort to paint but holding out some hope haha

You could try blasting with walnut shells, as they are the least abrasive, and see what it looks like. If you like the look, then clear coat it with a satin clear coat, but be aware, that the clear coat might peel away. If you don't like the look, you can always go back to the cast iron paint method. The cast iron paint spray is extremely good, and it doesn't look painted. Whether it be cast iron paint or clear coating, it is still painted!

Cast iron paint on the exhaust manifolds and brake drums were usually painted black. Bill Hirsch makes a high temperature black paint that comes in a spray can that works well on brake drums. Blast, wipe down with enamyl reducer to remove residue, and then spray.

Bingo! Clear coat is just clear paint.

For exhaust manifolds --> I suggest a cast-look ceramic coating. It should last for years.
I blasted my manifolds and painted them with VHT Cast Iron manifold high temp paint in 2015. Rust spots are starting to form, so I need to go back and touch them up.

I went ceramic, tried several other coatings and all bled through over time. No issues with ceramic after 5 years.

I did the ceramic coating as well. Eight years later, they are still in perfect condition. I suppose it has that 'over restored' look, but I like it.

Hi Dave, where did you get your exhaust manifolds coated?

Thanks evryone, Iam in the process of restoring the frame and the suspension. Would it be correct in assuming that all the cast parts left unpainted front the factory ? I was going to powdercoat everything semigloss black except the cast parts ? any guidance on what is considered correct would be greatly appreciated !
