Today was a bit of a rainy Sunday. So a perfect day to work on my cars, the Mercedes W123 in particular.
As shown in the previous posts, I had taken the little fuel lid of the car to take with me to the paint shop. When I got back I had a good look at it all and decided all the bits needed a proper cleaning and polish. I must admit, not very often I polish behind the fuel lid or polish the fuel cap. Still, I must admit I do like the end result!
Time to clean and polish:
When everything is clean and shiny, time to re-install the fuel lid. Bit of a fiddle to ensure it looks properly alined.
Next, to get the old rubber of the rubber strip. Which means a stanley knife and a lot of elbow grease!
Second phase of the rubber stripping. With my pneumatic tool and an abrasive bit.
Safety first of course!
After about an hours work, the metal strip looked like this:
Got myself some special glue that will glue rubber to metal. Also, this is Gel type glue, which I like which makes it a little easier to handle. It took me some hour and a half to glue to rubber seal to the metal strip. Very busy and no time for taking picture. So you have to take my word for it, it was a real PITA.
As I showed before there was a bit of rust. After properly cleaning the sills it appeared as only light surface rust. Still, needs treating. So sanded it down, masked it and sprayed it. Now, let me be honest, I am not particularly good when it comes to paint. The only reason I attempted it here was that it would be more or less completely covered by the new rubber seal, once installed.
With these spray cans, the trick is multiple very thin layers. I usually do three layers, each sprayed within 10-12 minutes of each other.
I also bought clear coat. This goes on 30 minutes after the last paint layer. Again, three layers, 10 minutes apart. Very thin.
The result was actually quite good, so I’m pleased with myself!
Waiting in between spraying the layers gives me time to clean up some of my tools, sweep the floor of the garage, or just listen to the radio. My home WiFi radiates into my garage. So with my iPad and my Bose Speaker I can listen to my favourite radio stations and stream whatever I like. Very relaxing.
After the paint had dried, it was time to re-insert the clips that hold the rubber seal.
Here you see one old one and two new one. The new ones you just push into the hole and then you push in the little pin in the middle. Actually, you need to take a small hammer to these little pins.
Getting the old ones off, is simple too. Some broke, some stuck in the rail and came off with the rail and some stayed attached to the chassis. I just hammered the little pins right through. That means it falls inside the sill. But that sill is full of Dinitrol oil. It won’t go anywhere.
The moment of truth, re-attaching the new rubber seal on the metal strip. I messed up initially and had to undo a couple of the clips. Wouldn’t align properly and I could not get the metal strip to click onto the clips.
Next I opened up the four jacking points. These are notorious rust traps on every W123. When I bought my W123 the car was in very good condition except for the jacking points. I had them cut out and new ones welded in place. There is an endless debate about whether you should leave the jacking points open or put these plastic caps on as I have. I’m not sure what is best. The rear ones seem quite ok, but I have quite a bit of rust on the front ones. So 50/50 chance I’d say!
But I like the look of the caps on the sills.
So grind down the rust:
Blow out the rust:
A lot of Tectyl:
I used some other rust proofing stuff underneath as well. Hopefully that will keep the rust to a minimum for the next couple of years at least.
Started on the rubber seal on the driver side too. Took it off, stripped off the rubber from the metal strip and did the respray thing:
I need to order some more of the clips. I should have ordered extra of course, but I ordered only twenty. As I buggered several of them on my first attempt, now I’m stuck. Still have to glue to the new rubber on the metal strip as well.
In three weeks time I have a long drive ahead of me. All the way to Bremen in Germany to participate in a Guinness World Record attempt to put the most W123s on the road. Obviously, I want my W123 to look as good as possible.
More to come
