1975 Mercedes Benz 450 SEL (W116)

Clean Dean

Keep it clean !!!
This week I had a 10 hour “project� that I wanted to share, because of the cars all original beauty. This 1975 Mercedes Benz 450 SEL (W116 Chassis) is not widely considered a collectible due to their high production numbers, it is very uncommon to find them in the condition as this one. This car is in my opinion represents Mercedes Benz engineering at its finest. These cars were years ahead of comparable cars of this era in regards to performance and safety.



I spent 3 hours under the hood refreshing an already fairly clean engine bay back to as close as it did back in 1975. Much of the original cosmoline was present, and all of the motors aluminum and stainless components needed gentle polishing (0000 steel wool) after carefully removing the cosmoline and cleaning all of the painted surfaces under the hood. I used some of Eastwood’s Engine black paint to touch-up where needed.

Removed all of the vehicles carpeting and rear seat and thoroughly cleaned and treated all leather and carpeting prior to replacing. Used Meguairs APC diuted (20 : 1) on leather and treated with Colorplus Leather Softner. Carpet was thorough vacuumed shampooed and extracted. Look at the condition of the rubber pad under the gas and brake petal !!!

The vinyl door skins were also cleaned with Meguiars aAPC (10:1) and then treated with Stoners Trim Shine then wiped down with a MF towel to a matte sheen.

The exterior was gorgeous !!! I did a three step on the paint and waxed it with Collinite’s Marque d’ Elegance. The hardest part about detailing this exterior was removing compound splatter that was in every nock and cranny and under every piece of trim and emblem. Some “detailer� really did some rush job on this one sometime ago. The paint was a red metallic known as Inca Red. All chrome was then hand polished with Mass Metal Polish and 0000 steel wool. I have only worked on this color once before on a 1976 SL, and it is gorgeous !!!

Thanks,



Legacy99,



Paint process:



Extensive claying with AM blue to remove old compound residue.

First step was with rotary (Milwaukee 5460) and Hi-temps extreme cut leveler

Second step with Hi Temps Light cut and a green edge foam pad.

Final step 3M Utrafina with Edge white foam.

then Marque d' elegance



All buffing done by rotary.

Awesome work.
 
Just wow. Wow at the engine bay. Wow at the interior. (Okay, really wow at the interior.) Wow at the finish, and wow at the fact that you did this in 10 hours.



I love the color, and those body lines haven't aged a bit in 33 years.
 
Clean Dean- Well you *knew* I'd be all over this one, huh? ;) You sure do run across some wonderful Benzes!



Yeah, W116s are really something build quality-wise, and that's an incredible one!



Nice that he's still running the hubcaps instead of putting alloys on it :xyxthumbs



Was the Inca Red still the original single stage?



Isn't it neat the way those cars can be field-stripped for detailing and maintenance? Not all glued/etc. together like today's cars...the guys who designed and build the W116-era cars gave some thought to what would happen after they left the showroom.
 
Beautiful car and great job!



I love the big old Benzes!!!! Was at an auction and saw one of the big motor versions with 5K miles on it. Still smelled new. I tend to believe the old saw regarding that you go with BMW for coupes and Mercedes for large Sedans.

Heh heh...didn't you just buy a two-door Benz ;) Sorry, couldn't resist :chuckle:
 
Very nice and it still looks like new when cleaned up. Those old MB interiors were fantastic. Don't like those big US bumpers at all though.

Man, you got me there!



It almost 11 and I just came in from polishing in the garage because my wife let in about 1,000 mosquitos opening the garage door while I was working on what is now HER car.
 
Dean,

Amazing!!! You find some of the sweetest old mercedes and you have a real talent for bringing out all their beauty.



What is your trick for the cosmoline? I have a w126 that is has a ridiculous amount all over the engine bay. It is really nasty stuff.

It's not *really* cosmoline, but rather a wax-based rustproofing product.



It's actually very beneficial, great as rustproofing products go. The problem is that it gets dirty (well, OK, it doesn't look all that swell anyhow, but it's there for a reason).



The trick is to clean it without cleaning it *off*. If you get too aggressive with citrus-based products, solvents, or the steamer, you'll compromise it: if it doesn't come off completely (I'd only do that on summer-days-only showcars and note that it really oughta be there with regard to concours judging purposes anyhow) it'll make it look white and "milky", which *really* looks awful! Clean it as gently as possible 'cause if it turns milky you'll end up cleaning it off. Even then, if you're *really* careful, you can leave a thin film of it on the surfaces in question (but then you'll have to be really careful with any subsequent cleanups).

I agree that it really does a great job of preserving the engine, and care should be used when removing it. In this case, the protective coating had turned a nasty black color over time. It also seems to bake on to the surface and becomes harder to remove as a vehicle ages. From what I've read this coating is applied at the factory and is applied to protect the engine from the salt water vapor in the air it will be subjected to while the car is being shipped overseas.



As a personal preference, I have always removed all of the cosmoline from the engines of all the vintage Benzes I've ever owned, and just did a complete engine detail on my 1987 560 SL. This may not score points in a concours competition, but I do get overwhelming compliments from MB enthusiasts and they are usually blown away by the engine appearance.



My preference is a meticulously clean engine bay with all of the painted and metal surfaces cleaned and polished to look as new. What I do not like is when valve covers and other components are powdercoated or polished to a chrome like shine.
