Cleaning Shadowline trim

Does anyone know what to use to clean the shadowline trim? There looks to be some sort of residue on the trim itself. HELP!

How about detailing clay and some soapy water as a lube for the clay?

I have these weird water spots that won't come off of my shadowline trim. Next time I wash I am going to scrub harder to see if I can get them out. They are an eye soar with the rest of the car being sparkly!

No, I wouldn't clay everytime, but if it is something that came on the vehicle when new, it's worth a go.

And, I think that 3M makes an adhesive remover. I've taken old license plate expiration stickers off with the stuff.

Don't clay every time, you don't need to and might induce micro-marring. What kind of residue does it look like? Goo-ey? Greasy? Make sure if youre waxing or applying any kind of product to your paint that you check to see if it's trim-friendly. You shouldn't be waxing your trim..

Sorry for bumping an old thread but I've noticed this with my shadowline trim as well. I'm not sure where it's from... recently had the car in for service and they ran it through their carwash so maybe there.

On sunny days it creates a sort of oily-multicolored water drop effect and it's really weird feeling. It's not smooth at all, it's like the opposite, kind of like when you eat spinach - that feeling on your teeth. I'm not sure if it's something that's on the trim itself or if something has eaten away at the coating of the trim, here's some pics. I tried some regular soap and water with a microfiber cloth but it didn't really help it.

I'm not sure how long it's been like this, but I only noticed it in direct sunlight. Even in direct sunlight, I have to stand at a certain angle to see it, so if it's not sunny you probably won't notice it.





Any ideas?

I got it once after I used a crap car wash and noticed it after I got back home,
I thought its because they used shitty/aggressive soap.
i also heard that the king of screen wash you use might cause it. Somebody told me to Try to avoid those with ammoniac. But i cannot guarantee if thats the case...

I had the same thing after I used a touch less car wash. I used a cleaner wax to make it look like new again.

Sorry to bump an old post.

OP - the shadowline trim is a single stage paint. It oxidizes and turns to that ugly color over time. Your best bet is to apply a light polish to remove the oxidation and apply a good wax or sealant to protect it.

Well,
being the OP has not logged in since late 2011 ... I think you're just pissing in the wind.

And if you read a bit more on the shadowline you'll find that it is not paint. It is Anodized.

You are right, what was I thinking? Trying to share knowledge with the community. Pfft! Ban me now.

Thanks the the tip about the paint, I didn't realize that. Either way it works out the same in the end.

Anodized Shadowline trim

Anodizing is an electrolytic passivization process used to increase the thickness of the natural oxide layer (natural protection) on the surface of metal parts. The process is called "anodizing" because the part to be treated forms the anode electrode of an electrical circuit. Anodizing increases corrosion resistance and wear resistance, and provides better adhesion for paint primers and glues than bare metal. For cleaning this type of surface use P21S Polishing Soap using light / medium pressure
