Restoration advice: rocker panel trim

Post by 71Satellite98661 » Wed Oct 22, 2014 12:24 pm

I'm looking for advice once again. Rocker molding - my narrow, 71 pieces seem to be anodized aluminum, is that correct? What is the best way to restore these pieces? Is stripping the coating and buffing the piece recommended? I understand that if they are aluminum I would have to plan in waxing them quite frequently.

:help:

I think those moldings were bright aluminum - not anodized. Exposure eventually dulls the finish.

I have seen custom made pieces come out of our machine shop at work that are almost as "shiny" as chrome. If starting with unpitted aircraft aluminum, the process involves wet sanding with finer and finer grit, starting at 400 or so and going to 2,500. Then use a polishing compound with a low speed buffer. I recommend a compound called Simichrome Polish. You might need quite a bit for 2 moldings.

You could clearcoat afterward. I have a custom license plate, made by a machinist who was the previous owner, on the front of my cuda that was polished this way about 9 years ago. I've never touched it and it's still very shiny.

Shiny aluminum parts are anodized in a process called "Brite-Dip". It's really hard to find a shop that still does this. David Russell in Florida did some samples for me and while they're not as bright as factory, they're really nice. Tuff Wheel resto also provides this service. New repros might be cheaper in the long run.

The last time I searched, nobody was repopping the GTX rocker moldings..........

I read somewhere - probably here - that the upper surface of the "ribs" was painted argent silver while the radius end and bottom remained plain aluminum.

Seems like someone recently suggested a shop that restored aluminum trim. Anyone ever used King of Trim in San Diego?
