Everyone's worst nightmare......

So I decided to pull the 126 out of storage and perform some maintenance on her when I found this:



What is the best way to stop this? Looks like there is surface rust all along the lip of the fender. The car is undercoated, why oh why did they not just spray a little further?!?!?!

I'm not sure about everyone else, but that's definitely not the worst nightmare I can imagine ...

Here's what I've done with similar issues on my 300D. I am NOT expert at this at all ... you may want to get advice from someone more professional first ... but this has worked OK for me: Gently sand off the bubbled paint and slightly into the surrounding area so that no rust or bubbled paint is left. Then I used the POR15 system: http://www.por15.com/SUPER-STARTER-KIT/productinfo/SSKB/ The kit has instructions and comes with a metal cleaner and a metal prep solution, as well as of course the POR 15 itself. Paint a couple thin layers of the POR15 over the rust and slightly over the surrounding area. You can sand the POR15 to make it smooth ... after that I used a good body filler (I can tell you the brand later) and sanded that to smooth it out further. Then comes the hard part ... finding a paint that matches your color ... I had it easy since my car is white. If you can find a auto detailing supply shop, they can probably match the color. I sprayed on two thin layers of the duPont OEM color for my car using a gravity-fed sprayer (after carefully masking surrounding areas). I did not have a topcoat, but you can add that. Mine came out kind of sloppy because it was my first effort at painting, and my paint gun is terrible and clogged. But since yours is a small area it probably won't look too bad. Color sand it afterward. Bottom line: the POR15 really helps hold off the rust from expanding.

Touch-up paint may do the trick for that small spot, but if you need more or are having trouble getting a color match, try these guys (I see you're from Lansing):
Finishmaster
1434 Diamond Reo Way
Lansing, MI 48910
(517)482-9099

I used my local Finishmaster and they had DuPont OEM paint which they put in a pint for me. You can thin it and put it in a paint sprayer. They would have clear coat too.

Grind it down to clean metal, prime it with rust stop, paint it with touchup paint - then put chrome wheel well trim all around.

I've been watching a rust spot grow on my trunklid since I bought my 300cd... funny since that's the only body rust to speak of. Grinding and matching metallic paint scares me more than the rust spot. Whatever I would do to the spot would look worse than the bubbles, I'm going to wait until I repaint my Subaru to work on my Mercedes.

Grinding on your metalic paint is not as scarry as rust. rust never sleeps, it keeps growing.

POR is a great product, and does work. You will need to coat both sides if possible. the bubble may only be the tip of the iceburg .

There is a touch up gun, think the name is Prevale. it is a pressurized top piece with a spray button, and the bottom has a screw lid that screws on a bottle that comes in the kit.

then buy your PPG or dupont paint, primer, and reducer, etc. It works ok for a small area, best to practice on an old fender to get the hang of it. Be sure to buy a spare pressure piece, nothing like almost finished and phssst your out.

I have used these but my Accu Spray HVLP gun works better .

For small spots I would just take a screwdriver and scrape away the bubble to expose the rust, apply rust binder and touch up with matching paint applied with a small brush. Most important is to stop bubbling areas like this before they get bigger.

I would never install the chrome lips, they create a place to collect dirt and salt and rust.

My worst nightmare contains evil clowns.... but that's a different story. That's not too bad if you get it now. I agree with the others. POR-15 or Eastwood Rust Encapsulator are great products. Then mask it off and spray a little singls stage on there. Lightly sand and buff it out and you'll hardly notice. Later, if you leave it alone, you will definitely notice the rust hole.

A fellow Michigan MB owner! How are things in Lansing?

If you see a silver-blue-metallic 300SD or a Smoke/beige 300E driving around in Lansing, that is most likely me...I am there from time to time.

I was going to say that. Aside from being aesthetically un appealing (okay that's just MY opinion), those chrome trim pieces seem like a perfect place to capture salt and create a REALLY nice rust spot.
