Hard plastic window trim oxidation

I noticed the trim around my windows has lost its luster.

Sorry, I don`t have a digital camera so I`ll have to describe it.

It looks almost like it has oil on it...you know like when you look at it from different angles there are opaqe color swirls.

And at the same time its dull...no luster at all.

I am assuming this is what is considered oxidation.

It`s hard plastic (still smooth to the touch)and is supposed to by shiny.



I`ve searched other threads but I haven`t been able to tell if the window trim in those threads were rubber or plastic.



Any suggestions are appreciated.

when you clean it with back to black or the liking does the towel turn black??If so Id like to know the answer to solve this problem too,

Mike,

Use AIO, a few terry applicators, and terry towels. After the first two or three applications, the applicators and towels will come out black. You`ll see the natural color return to the trim. When you are no longer removing black color (or at least, very little), top with a layer of SG to protect.



If you don`t have AIO or SG, go ahead and purchase AIO and SG:)

I haven`t done anything to it yet.

I didn`t want to try something on it that might make it worse.

I`m sure that there must be something to make it look at least a little better....... I just don`t know what .

MPPC - Meguiar`s Medallion Premium Paint Cleaner removes the oxidation for me. Sometimes takes more than one application to get all the oxidation. Then I like Zaino to protect the black trim, seems to hold up better then anything else. Most auto parts stores carry MPPC (black bottle).

Thanks for the product and techinique tips.

I can`t wait to try them out.

Maybe it`ll work on the drip molding...it has the same oxidation problem.

Yeah, try the paint cleaner/sealant combo. Besides the ones mentioned, you can also try zaino, VM, and topping the AIO with BF. The only thing this approach has *not* worked on (at least for me) is the matte black wiper arms on the MPV. They look crappy no matter what I try, so I just use this approach more frequently and let them look imperfect.

Any paint cleaner will work. I like to use AIO, UPC, MPPC, poorboy`s PP, or whatever else is on hand.



Accumulator, my wiper arms are the same way. I try to keep AIO, UPP on them. I have used WD-40 on them a few times and seemed to last. I stopped because I was afraid of long term damage. What do you think?

I dunno, I don`t use WD-40 all that much. I wouldn`t *think* it`d cause any problems though. And wiper arms (at least on a normal, modern car) aren`t all that big a deal...replacing them wouldn`t be a huge expense in the unlikely event that the WD-40 *did* do something nasty.



My only real concern is that the WD-40 might cause some slimy transfer issue...e.g., getting it on a wash mitt and then getting it on the rest of the vehicle.

Understood, I like to apply it with a deicated foam applicator, allow it a few minutes to "penetrate" then buff off with a general purpose towel.



Thanks!!
