Rear Diffuser Removal & Refinish (Pics)
While I like black as a color for an S Class, it loses some of the contrast with the AMG body kit that a lighter color has. I decided to experiment with shooting the rear bumper diffuser a lighter shade of gray to distinguish it from the rest of the bumper.
Along the way I discovered how easy it is to remove the rear diffuser, after which it can be painted, or vinyl wrapped in carbon fiber or whatever.
The diffuser snaps into the bumper with molded-in tabs around the perimeter. Given how much of this car snaps together, I'm beginning to feel like I bought a $50,000 Lego Set. The tabs are very sturdy and require just a bit of effort to pop them out.
Before you get to the tabs around the perimeter, on the underside of the bumper there are two tabs on the diffuser that need to be pushed upward and outward. There are also two plastic clips (see hole in the pic of the bumper detail) that need to be pulled out.
It's easier to demonstrate with the parts removed. The first pic shows the "male" tabs on the underside of the diffuser, and the hole where a small plastic retaining clip lives.
This pic shows the location of the "female" side of the tabs on the underside, one near each tailpipe.
Once the two tabs and clips are released, just tug around the edges of the diffuser and it will pop right out. Mine had a nice V shaped gouge in it where some yahoo at Home Depot had backed something into it. I used a sanding block to even the surface out a bit.
Reinstalled after refinishing. I used Krylon Universal spray paint made for plastic. First I sprayed an undercoat in a medium silver color for depth, then a finish coat in a charcoal color (Flat Iron).
It's a subtle change and still looks OEM, which I like. I think I'll try getting the carbon fiber wrap and see how that looks, but this is a good interim step.
The front grilles got the same treatment.

Start by pulling the outside of the lamp away from the bumper and you'll feel the tabs holding it to the backside of the lamp. Push them to release and then rotate the bulb to fully remove the lamp.
To install your new lamp you have to peel back the fender liner enough to get a hand in to the backside of the lamp retainer and hold it in place while you snap the new lamp in. Takes about 15 minutes total..

So in your opinion do they look aftermarket or do they give a better look , I see the one you have ,which looks good ,but do the cool glass look and match as far as quality .as ALWYS thx

I think the idea is to make them disappear so there isn't anything distracting the eye from the car's lines so they need to blend into the surrounding paint color as closely as possible. On a light color car I'd just want a clear diffusing lense rather than a bunch of tiny LEDs exposed. In terms of quality there's not much to either the OEM or aftermarket pieces...just a plastic housing and a plastic lense. The units I bought on Ebay have the same look, feel and weight of the OEM pieces.
