Re: Cleaning/Polishing Portlights

These are exactly the same as mine, and mine are cast aluminium.
Mine were in terrible shape, and very pitted, they are the original, from 1967.
To re-anodize them I would need to polish them pretty good, a difficult job and expensive to outsource. After polishing they would still need to be dipped for cleaning then anodized. A 3-step process - polish, clean, anodize.
I opted for cleaning them as good as I could then prime with Boeing-spec primer and painted with two part Polyurethane. Sounds like a long process, but I did the cleaning and paid for the prime-paint. It was inexpensive, much less than the re anodizing process.
Be careful if you just want to clean and polish them - by using abrasives you could remove the anodizing and they will be prone to corrosion and pitting.
