Perhaps the effect you're seeing is similar to what some "glaze" products do on paint. Stuff like Meguiar's #7. Which might work too. Interesting.
If you remove the anodize, you can polish the trim, but you'll have to do it very often. Like every few weeks, not months.
Good point Rick. I believe the blotching that we see is happening below the anodized finish between the aluminum and coating . The "Wesson oil " treatment is just that........ a treatment that will probably not holdout as a permanent fix but it will do for a band aid ....... if it lasts a decent amount of time it works for me. It is easy to do and can be done along side of detailing the car. Replacing moldings will be left to an overall paint when one blows the car apart for removal of the trim. I've been checking it daily and the results are positive.
