Beautiful Cobra Tim, much better looking already then it did going across the block on TV
I don't know what you're using on the body (Polish) to get the fingerprints, swirl's, etc. off, but I collect vintage stereo's from the 70's with brushed or polished bare alum. faces, the lettering is paint, so you rub too hard, the lettering comes off, and it go's from a perfect vintage stereo, to a garage stereo real quick
I have tried EVERY Alum. polish out there, and what I use on all my alum (Bare) piece's is 'Blue Magic' blue Metal polish, cleans Alum stereo faces without removing the lettering, also great for alum. wheel's, valve covers, even my plastic turntable covers, newer plastic headlights (Remove's fine scratches). Might be worth a try, if you haven't tried it. Hope this help's. Glad to see your driving her
Cheers Tom.
