My 924 is white and all the black parts (bumper sides, mud flaps, bumper pads, etc..) are fading and looks very bad. Does anyone have any solutions for this problem? Do you think something like Armorall, or tire shine products will work to darken or give a nice deep black look again? I know anything you would do wouldn't last long, but just something to look nice for a few days.

Oh my, there's gonna be a row over this question.

After many, many years of prepping cars for shows, I really like Vinylex. It takes the wax off the black rubber and makes it look brand new. And it actually does last a while -- like all summer. Amazing stuff.

I do not use any of the "off the shelf" products like armourall or STP or that kind of thing.

JMHO.

Two things that I've used that work pretty good are Goof-off and this rubber restoring chemical used to recondition the platens on typewriters (the platen was the black rubber "rolling pin" that the paper wrapped around and against which the typewriter keys would strike). I don't know the name of the latter product, might be able to find out from Larry my Rustang buddy who owned the typewriter repair business. But Goof-off has worked pretty good for me.

I hear black paint works pretty well.

Ardex 6224 Speedy Brightener - http://ardexwax.com/Product_Page.html#Dressings
Silicone based (good for rubber). I've used it, and each treatment lasts a long time.
Ran out - I need more. When I had it, I'd apply only once or twice a year.
First found it at a small pro detailing shop 10+ years ago. It took about that long to finish the one bottle.

I use the same stuff they use to make tires look black and wet.

Sandblasting works well too.

In terms of plastic parts, I use (and have been really happy with) Son of a Gun by STP. It's nice to know that not only does it restore the luster of that black trim, but it also offers a certain amount of UV protection. Haha, look at me... I'm the Son of a Gun 'poster boy'.

But seriously. If you haven't tried the stuff, get some. That 'Forever Black' product works pretty darn well too. Personally, I stay away from rattle canning, but I've been itching to try that new Fusion plastic paint by Krylon. Anyone had any experience with that stuff?

There are a lot of items out there, I prefer to use Poor Boys products for detailing....

I avoid off the shelf items from parts stores.

Go to www.autogeek.net you will find a wealth of knowledge and items to chose from...

Dura-gloss products are what I recommend...

...of course if you want a better, more permanent fix... BionicBalls is right, you should paint them. The bumperettes and mud flaps are essentially the same plastics that modern cars use as molded bumpers. These plastics are not difficult to paint and are usually painted right along with the car...

However, for you to do this will take the proper prep work... after that, any automotive paint should do the trick since it's flexible and very durable.

The results will be far exceed anything you could ever apply, and will last for years to come.
