Does anyone have any recommendations on a rubber seal conditioner/lube? My sunroof and rear doors seem to be creaking in my C450. Thanks in advance!

Gummi Pflege seemed to work for me. I’m not a fan of the application style but It does the job.

nextzett 91480615 'Gummi Pflege Stift' Rubber Care Stick - 3.4 fl. oz

Thank you! I read about this in another forum. I saw some reviews on amazon saying that the seals started to leak after applying this product. Do you have a panorama moon roof on your car?

GreekUPS

I have applied to my pano roof and just about every door, trunk, and hood seal. Never had any issues with leaking.

89Benz300SE

Awesome! Thank you, I will order some and when it stops raining next week, I will put it on.

If it's creaking, also try Mercedes Sliding compound / Krytox. Permanent solution and safe for rubber seals / surfaces

would you happen to have a part number or a site to buy it from?

You bet A0009893560 (dealers should stock it)

It's not cheap, but you will never need another bottle - a few drops go a long way (and wear gloves!)

Found a great price for US

Gummi Pfledge works great..... most folks I know pickup a tube of the Honda product. you use a vinyl glove to work it into the seals...

Gummi pfledge comes in two types a stick much like a deodorant or in liquid form with a sponge on the top of the bottle.

The liquid type is much easier to use.

I will have to give the dealer a call and see what they charge for this stuff. Or shop around and see if I can find a good deal somewhere.

Thank you!

Maybe the dealer will price match it.

Gummi bears?

I use Krytox too on the door seals and pano roof, very effective

MBSebas87

How often do you guys apply it?

Mikesmith2939

I apply Gummi pfledge about every 4 months.

I've had a bottle for about 4 years now.

Amazon currently have two bottles for under £20 delivered.

Dielectric grease is the only thing that really lasts

89Benz300SE

Is that safe for the rubber seals? I am not sure what dielectric grease is made of

fabbrisd1

Diaelectric grease is a type of silicone - sure a tube/can is under $10 - but frankly in silicone I would recommend speding $5-$6 more for the Honda Japanese made silicone designed specifically for door/sunroof seals..

89Benz300SE

I ended up buying the gummi pfledge. If it doesn't work for the creaks I will try one of the other products suggested. Anyways, I can use the gummi pfledge to recondition the 31 year old door seals on my 1989 300se.

A good piece of advice was given here a few months ago. Don't open your sunroof in the deep midwinter, unless you are where it's warm.

GringoBling

yes, it is grease made specifically and only for rubber. It's used to insulate coil packs from the plugs.

Kartergreg

The Honda silicone grease is very good. Learned about it in our Plymouth Prowler group and have been using it with great success. Available on line thru Amazon.

FWIW......

I saw in one WIS instruction, MB had a official / recommended lubricant for rubber used inside the engine compartment, the item was part number 000-989-03-67 "Sliding Fluid - Mercedes-Benz".

For everyone's information MB published a document titled: "Mercedes-Benz Genuine Chemical Products" Product information for aids, operating fluids, accident and body repair - 66 pages, a PDF copy at :
