Manifold restoration
Ok so I have tried all the aluminum cleaners, mag wheel, etc.
What can I do to make this look original? Bead blast? Don't want to paint it.

Re: Manifold restorstion
Don't thing of the spices on the range will work! Probably sand with progressively finer paper until pits are gone and polish with compound and buffer wheel. Cast alum usually has a "grain" and doesn't polish like solid alum, as in billet.

Re: Manifold restorstion
I used Paint stripper on mine. Left it for 30min and scrubbed off with scotch guard.
Worked for me. Kpar |

Re: Manifold restorstion
I would also blast it, then spray clear lacquer on it.

Re: Manifold restorstion
I would also suggest glass beading, and then spray paint with Aluma Blast. This will keep it looking like it just came out of the bead blaster for years.
I have in the past used the various different clear coat paints that are available in rattle cans, from many different sources, and it has always caused the bead blast finish to turn a dull gray color as other folks have already mentioned.

Re: Manifold restorstion
Soda blast should clean that up to the original cast look.

Re: Manifold restorstion
remember that the abrasive blast media is very hard to get out of the internal passages----untill the gas/air mixture moves through the manifold, then it will lap the rings and cylinders----I have seen the results, about the same as pouring sand down the intake

Re: Manifold restorstion
Try steel wire brush on drill to polish. Large brush on drill for large areas, use small dremal wire brushes for small areas, crevices. No residue and nice semi- polished finish, if that is what you want..Maybe too shinny for original?

Re: Manifold restorstion
Probably the worst thing you can do if looking for 'original' as cast finish.

Re: Manifold restorstion
Yes, yes, yes. Glass beading is the only way in my opinion. Clear coat is optional but does help maintain that "new " appearance. Eastwood sells a clear that holds up well to heat. I have used it and it does as advertised.

Re: Manifold restorstion
Wire brush (really about any type of brush) will leave marks on aluminum. If you want to retain the "cast" appearance do not brush it!

By glass beading the outer surfaces (not on the bottom or inside the two venturi openings on top where the carb mounts) and then spray painting the outer sufaces with Aluma Blast, you will have a finish that looks very much like the original finish, plus it will be resistive to fuel and other types of stains for a gooood looooong time.

Re: Manifold restoration
Anyone ever tried walnut shells instead of glass beads?

Re: Manifold restoration
Here you go I have seen many failures due to poor blasting projects.
