If this helps someone, it will serve its purpose. Over the last five or so months, my OEM window visors started oxidizing (I know this is a very common problem). After reading through many threads on AZine, people seemed to have success with a few products, namely these:




Unfortunately, the oxidation on my visors was so bad that these products didn't work. Actually, they made the problem worse. I was going through my products in the garage and forgot about one that I use when I do my annual buffing:



Below, you can see the oxidation. This stuff wouldn't come off for anything. After 5 or so minutes of just hand-buffing (no need for orbital), here was the outcome:



If anyone has been unsuccessful with other products, you may want to try this stuff. It is a bit more expensive (read professional grade), but it worked...at least for me. I simply applied it with an old sock (preferably clean!) and wiped it off with the same sock (dry part). I used one sock for each side of the vehicle. It took about 20 minutes total. I would recommend doing it before you wash your car (rinse visors before you start so you can eliminate any loose dirt/particles as to avoid scratching), as it will cause wax-like dust particles. I hope this helps someone.

I have had mine on for 4 years now and I have kept them fresh just with a layer of any good cleaner wax BUT it has to be done regularly .

OP I think a lot of your oxidization was in fact water spotting by the pattern on the undone portion and the water spots on your window.

The first 3 products aren't effective on water spotting but any good polish is as its abrasive.

Now that you have gotten them looking good apply the PlastX then a good sealant.

 

Nice recovery of the visors!!

 

Thanks for sharing, man...since new, I've made sure to add some sort of polymer protection, same I put on the paint. Hoping it never ends up looking chalky like that.

 

good to know! thanks for the info!
