Default Plastic Trim Fading Problems...

My subie is experiencing some serious paint fade on all of its plastic bits -- i.e., both bumpers, side-view mirrors, and grill flanks. In fact, when I go to polish or even wax these parts, I can see my paint coming off onto my applicator... What gives? Do other people have this problem? It's as if my clear coat has totally disappeared from the plastic parts!!

Needless to say, it's starting to become really noticeable, and it looks like $%@$%.

The only plastic parts I've had to fade were the black ones, such as the trim piece below the wipers, and well the wiper arms themselves also need to be repainted.

Do you buff on the car very often? I feel like that would be the only way you would have cut through the clear.

What exactly do you mean by "buff on the car"? I did everything the same as I did on the rest of the car, but everything that's metal looks fine and normal. I never see paint coming off of the metal pieces when I'm applying wax... I just don't understand why it's happening to the plastic pieces only.

Over zealous waxing and polishing of the paint can cut through the clear coat on edges, but it seems improbable that is what is happening to your painted plastic parts.

That seems odd. And its the first time I have heard of someone having this problem. The bumper covers are plastic as well, are they fading? Is it the factory paint?

I believe the OP is referring to plastic parts of the car that are painted body color, not my mentioning of black trim plastic such as side skirts.

yes alot of body kits have this same problem, im a car painter if you repaint it you can buy a flex-able agent to mix in the paint it makes it bendable and not chip off good for plastic materials that you paint over.

I am referring to the painted plastic parts only. My black plastic parts are fine (they're not painted).

I can't understand how the plastic parts could fade prematurely from the rest of the car when it has all been polished/waxed in the same manner. I've heard from some people that the plastic parts receive different paint treatments, and this might account for it. One person told me that my plastic parts probably didn't receive the right kind of primer, and therefore are aging differently... does this sound possible?

Anyway, unfortunately I think the only option at this point is to have these parts re-sprayed. The car has never been repainted -- it's all factory paint right now.

If, when you polish these items and the color of your paint can be seen on the cloth, then somewhere along the way some one may have repainted these items in a single stage paint with out clear. This could also explain the fading...

Clearly people are still getting confused between painted plastic parts and the black plastic trim.

.either way hes still wrong. There are non-staining sealants/waxes that I have found work quite well on some unpainted trim. In fact, I prefer to use a sealant on trim bits vs. a dressing when possible.

Clearly people are confused, and some people are just putting out some wrong information like wax and plastic fading haha.

OP A bad paintjob with either poor prep or clearcoat failure (or both) is what I would suspect. However, paint can come on to a pad if you have a single stage paint job on these parts and using and aggresive pad/compound combo. You did say waxing so that makes me want to dismiss this item. If paint is starting to flake or come off onto the pad, there is really no detailing products that will stop this from escalating.

Your best best is to get a professional re-spray blend in these areas.

Pictures would help a bunch. Also, what are you using to polish?

Also, staining and fading are too different things. Some waxes/sealant will stain, but I have never used one that faded plastic, even if it did temporarily stain it.

I'll post pics tonight if possible.

I typically use Meguiar's stage 2 polish (every two years I might go through step 1 polish which is more abrasive -- but that's not the norm). Then I follow up with their wax or with nxt generation synthetic wax. But before all of that, I usually either clay or wash with dish detergent to get the old wax off.
