Gee there is a lot that doesn't look good with that one rear panel. Is it the same on a sedan if you could find a donor? Is it short enough to freight without crazy cost if you could source a new one? I reckon it would be worth exploring and then see how much would be quoted to get it all straight and rust free as is. Also with your bare metal it would be good to wipe some metal prep / phosphoric acid over it to stop surface rust. I've only seen it at proper paint suppliers, but one bottle will last your whole project and really easy to apply - wipe on and wash off and then it leaves this coating that you don't need to remove - can work the metal etc. and then wipe on some more at the end of the day. Just keeps this phosphate coating on there at all times and stops any risks of paint issues later.

Phosphoric acid is available at Bunnings. I restore rusty fasteners that are hard to get by leaving them submerged in the acid, then bring the fasteners to the platers.

Nope, a Finny sedan rear panel is quite different. Taillights are much smaller on a Coupe.

I reckon a W108 rear panel comes closer....

how much does it cost get bolts plated? Zinc I presume? What sort quantity do they prefer?

For zinc plating:

It goes per kg. You can mix and match smaller and larger pieces. But I paid about 15 dollars per kg I think.
This was with a yellow finish, which is an additional process.

They do an acid etch before the plating process.

I know what you mean Craig, I keep looking at it and wondering if a good panel beater could repair the existing and if he spent a week fixing it up that might cost less than a new part. I might even consider welding in a whole panel myself;

New parts exist:

http://www.oldtimerservice-vornhagen.de ... ::871.html

The price is the price, but I've tried this with the boot floor and the size of it means DHL wont ship it and it all stops at that point. I've found others in America too, but the price there including shipping was near $5k, and for that price I might as well get a decent body man to spend some time on it.

Might have to fly back to Germany and help Thomas with his ute and pick up a few parts for the trip home!!!

What I have done with sills, is cut them in half for shipment and then weld them together on the other side.
Works fine, if you use those 1mm thick cutting discs.

It can be done, but you need to weld carefully. To your advantage, finnie steel is quite thick...

Craig, I've got a big tub of this stuff, I'm assuming it's the same

yes good point - I think it says you can treat panels and leave it as a coating for a certain amount of time... from memory. I imagine at least as long as the phosphoric acid. Mind you, i bet the phosphoric is a lot cheaper but I wouldn't use that under a KBS paint or use on proper rust like you would use rustblaster - would only use as treatment on unrusted to seal it.

I neglected to take a photo, but the fuel flap cover bit is completely knackered. It had rusted through at some stage and was completely filled with bog. I was picking it back to see if I could patch it up and use it again, but it's too far gone.

I've got a feeling a w108 is the same?? can anyone confirm that?

below is a photo from ebay of one that looks identical, it has the hole at the top to allow you to open it - I think sedan ones are different??

Can you send us a picture of your existing fuel flap?

I am pretty sure we can sandblast it, and then close the holes by either welding/leading or brazing.

I might even have a go at it for you (if you pay shipping to and from Perth)
We have a blasting cabinet at work I can use, and then I will submerge it in phosphoric acid.

Thanks for the offer bart, I'll get a photo tonight.

It's not the main plate that's a concern, although it's holier than a church choir, it's the internal strengthening part that is spot welded in at the top and seam folded in a the bottom, it's all rusted out.

It will make sense in the photo when I post it.

I think I can confirm that the part number is the same for w111 coupe and w108 sedans - A111 750 5606, so I might as the forum if anyone has a good condition w108 fuel door that they want to part with, that would save a lot of head scratching and fabrication.

There are a few on ebay from Germany also, various conditions and prices as always.

Hey Bart,

Here's the photos of my fuel door, the whole bottom half is a bit rusty, metal very thin and all bent out of shape, I'm saying it's not really salvageable. I'm happy to weld rusty metal but in this case I think another one is in order.

Here's few photos from the weekend, have now stripped the rear three quarter panel and door from the passenger side, door is in reasonable shape, but the rear three quarter has been in the wars, lots of ripples in the panels and a lot a large patches.

Have started on the roof too, so far so good, a couple of minor dents to be pushed out and a bit of rust at the rear edge, all fixable. I'll finish up the roof this week and then onto the bonnet and engine bay.

I see what you mean. It is double walled.

Anything can be repaired but if a W108 piece fits than that should be the obvious solution.

The stripping of the green continues. I figured everyone has their favourite 'did you see how thick that body filler was?' story, so here's mine, the front fender has been cut and shut at some point and left very low, the shape being made up by nearly 10mm of body filler. I've finished the roof too, but didn't get a photo. The roof is in ok shape, a couple of dents where it looks like something was stored on top of it at some stage.

I've started on the engine bay too, uncovered a bit more rust that I missed first time round, so will need to break out the welder again soon.

Getting there.

More work in getting that bog looking good than doing it properly in the first place.

Hey Sebastian,

My tail panel has been repaired in the past - looks like accident damage. It’s not in great condition. I have seen them for sale at about 1800 euros, plus shipping, I can find the website if you’re interested. Shipping out of Germany for such a large piece is also difficult.


I have managed to get the passenger side floor in, just working on repairing the cross support boxes at the moment. Hoping to have them completed next weekend
Thanks Eddie for the info. Unfortunately 1800 + shipping is way out of my budget. I will have to manage how to fix, it is a lot worse than yours.

We'll see..

Hi Sebastian

I know what you mean, the costs for spares on the w111 far outweighs the pagodas and other Mercedes except for the Gullwings in my opinion!!!

Keep at it!!

Little update. I stripped the bonnet the other day, few small rust spots, but generally pretty good. This time I did as per CraigB's suggestion and wiped down with the phosphoric acid, so will be interesting to see how it goes. I've noticed the panels I've stripped earlier are starting to get a brown/red sheen on them, so I will have to revisit them. The acid process was quick so no big deal.

I'm currently tidying up the engine bay. Will post a picture or two soon.

Phosphoric acid is used by cow cockies (dairy farmers) for cleaning their milking plant . That means you can buy 25 liters for around $70 from farm supply places . Mix it with water about 6-1 ad it works great as a rust convertor and metal prep.

Great tip Mercmad !!
