Interiors & Exteriors / Re: Dinitrol rust treatment?
Last post by rumb - Today at 08:18 AM
It looks like it is a cavity wax. I wonder what the effect would be of spraying wax over existing rust. I suppose a good layer could keep oxygen away, but would it also stll allow rust to grow underneath at all?

On w116 the majority of the original shultz is usually sound, but its the edges that have broken down and then allow water to go to work. Also most of the rust is inside something, not on an outside surface , like wheel arches and rockers and it is loose rust not just surface.

The rockers have plugs front, rear and all along the top edge. I would be more inclined to spray a rust converter in all those plug holes after first blowing air in the holes to remove as much crap as is surely in there.

The wheel well, esp rear remove tire and find any loose edges with a screwdriver and peel or grind back to expose all rust. Then convert it and then the wax could go over that, or just use some new schultz.

Warning though what may look like surface rust can easily become a hole when you start picking at it.
Interiors & Exteriors / Dinitrol rust treatment?
Last post by SteveDuNord - Today at 05:06 AM
I've found a local business that offers dinitrol ML treatment, starting with a wire brushing. They keep the car for a few days and it's their sole business, so I would expect a proper job.

Has anybody used this product on their 116?

I'm just surprised Mercedes still sells many new parts for these 40+yo cars! The market for these items must be minuscule in their eyes, even aftermarket parts seem to be plentiful. Try and buy genuine parts from Ford for a 20yo car and you will be struggling!

Can any one share their opinions of the"refurbished" units on the market as well as the "mini-computer"?

Hi guys,

a few points from a right hand drive perspective
-227 australian cars officially sold in 70s, but i have records on 290 or so in australia over the last 20 years
-287 cars in the UK, stated in Evo car magazine issue 98 (this was in my database for some odd reason). i think this is low if we got 227 here in australia.  i briefly took records on UK cars as RHD vehicles and i mean briefly in the early 2000s, there were at least 20-30 i had.

the remaining and nice cars is a valid distinction.  different markets have different fates but i would say at least half of australian cars are still going. it doesnt mean they are registered though.
nice ones the number would be over 500-1000 i think quite easily. of 25 or so 6.9s in my little state of 2million people, about 8-9 are cars you would look at and state they are a nice reasonable car, probably 5-6 you would say are slick.  people have different definitions of this but im no pushover on quality (but also realistical).

the value query creates 2 polar opposites of opinion Neil.  i agree with some points that the cars could be aging them themselves out of demand. But in recent years we have seen 6.3s go off, 600s plateau, and now 6.9s take off unrelated to covid car prices.  in saying this, even i would likely (and have) declined a 600  as knowledge to keep them going scares me off a magnificent car. 

ultimately, everyone has their own opinion.  my own 6.9 has been with me 20 years, will unlikely never leave me, but only gets driven <500km a year as its part of a small MB collection I have. i would include it in the tidy group.  the link is a video of my 6.9, and dads which was a massive resto 10 years ago. dad drives his everywhere regardless of weather.

Another blue one popping up again is #6225 in Victoria.  Bought by current owner in 2016, its on carsales for $44,000.  An australian car with the rare velour (for our market anyway, as essentially all had leather), it has no radio.  same seller attempted to sell a couple of years ago.  it has 284,000km on it. it has had accumulators done recently PS the forum update is really making mince meat of attachment of pics. sorry about this!

Quote from: rumb on 31 July 2022, 01:40 PMPerhaps start considering sending the WUR and FD to CIS Flowtech for testing and calibration?
i called them today in my darkest hour.  They're 9-12 weeks out!  wtf?

They're that good.  It's worth the wait.   No one else in the U.S. can come close to how good they are at what they do. 
good perhaps but not perfect.  I got a rebuilt WuR back from them about 3 years ago.  It was all fine EXCEPT for fuel enrichment, which was about a 1.2 bar drop rather than 0.5 orso (coincidentally one of my recent problems).  Basically it didn't work.  By coincidence I had another working WUR.

We shouldn't let one mistake condemn them.  No company is perfect. 
That's true, and I don't.  Unfortunately my sample size is 1 and it was a dud.  And as it is, I'm back in business with the car.  So I'm gonna send it back and let them have at it again.

On the used as daily driver or not, I have seen way more US 6.9s with low mileage than higher mileage (maybe just because the high mileage ones are dead and gone).  I have the impression most were bought by owners with multiple cars and multiple car garages.  Either way, as others have said, unless someone keeps making some of the specialized parts we'll be in trouble.  I also own a 190SL, you can pretty much still buy that car piece by piece still (but some of the pieces are expensive).  Hopefully at least the W116 replacement type parts stay available and then a few specialized places worldwide continue to deal with the 6.9 items.

Quote from: rumb on 13 August 2022, 06:06 PMI was searching for 6.9 for sale and found a few asking as high as $117k in europe.

Somwone thinks they are valuable.

Within about 10 years all the parts ones will filter out and only the small number will remain most in fine form. Parts will become sparce to restore then condition and remaining rarity kick in.

Rarity doesn't always mean valuable.  If there is no interest, then it matters not whether there are 10 left in the world or 50.  Without interest, values will remain stagnant.  The 300sel 6.3 and the 600 are good examples in this regard.
