The factory finish was a 'dull lustre', while the NOS ones from GM are much shinier - if that's a word. I've learned that if you glass bead them they will lose all lustre. Some guys have had them tumbled in various media with mixed results - likely walnut shells or plastic media is best. Finally, Jerry McNeish offers a 're-skinning' service that has been well received. The rest of us simply buy the best original condition ones we can find and rub them out by hand....

I blasted my thermostat housing with 100 grit sand and then tumbled it in ceramic media and it came out looking like new, or at least I think so.

Did mine by lightly blasting with low pressure glass beads then 0000 steel wool to put a light shine in the peaks of the fins to put a very light shine on the flat surfaces. Had to do it twice to get it where I wanted. The key is to not rough it too much in the blast cabinet. I used about 40 psi, just enough to pick up the media and stayed about 8 inches away from it. Just enough really to clean the surface and even out the surface.
I then followed up with the satin finish Ever-Brite to seal the pores and make them easy to keep clean.

I recently cleaned up the valve covers for my 71 LT1. I feel like they look right as far as the finish color etc.
I used organic PH neutral cleaner then used neverdull cotton wadding, however they were not too dirty when I started.... The FIRST PHOTO IS FINISHED TWO SECOND PHOTOS ARE PRIOR TO CLEANING.

I used some walnut media in my blast cabinet, followed with steel wool. I think I could have used glass bead at low pressure with similar results.
