How to apply MB Seal Lubricant?
As a result of reading a few posts on here about lubricating the roof seals on the SL, I finally managed to acquire a bottle of the recommended MB lubricant from my local MB stealership.
Cost = £40 (Ouch)
The only instruction supplied with the bottle is the BIG RED multi-language label waning about getting the stuff on anything but the rubber seals and throwing away ANYTHING that this stuff touches apart from the rubber seals.
Question - Is there anybody on the forum that has actually used this stuff and if so, what is the best/safest way to apply it?
Many thanks in advance for your valuable assistance.

Looks like the bottle of Krytox GPL-105 that I have.
Get some IPA and give all the rubber a good clean with a cloth.
I used my fingers to rub it in. It is apparently suitable for the food industry so it should not be a problem on your fingers. A little goes a long way. Don't get it where you don't want it, it never comes off.
My came with a screw on cloth applicator and the nozzle.

Most people use gummi pflege or some sort of silicon (silicone is not generally recommended) . Your seals may be coated with one of them. Krytox (if that is what you are using) should go onto a nice clean surface.
IPA is form of alcohol but without other gunk in it. You can dilute it with water by about 80% for cleaning.
I'm new to krytox but from all I've read it lasts for several years and is what teh manufacturers use.
Gummi Pflege which I used on my SLK, needs reapplication annually.
Gummi Pflege is cheap. Krytox is expensive.
It is worth doing.

Do NOT use alcohol on the rubber seals. Clean with water and mild soap if necessary.

I used the Krytex GPL 105. My application was simple, wipe down all of the rubber seals within the vehicle. I have the SL so, I held the top partially open while doing this entire process. (Yes, the top will either close or open completely while doing so after a period of time, I just worked around it). After cleaning the rubber moldings/seals. I applied a small amount of the Krytex along each seal. With a rubber glove on, I smoothed and rubbed in the Krytex in a very even covering fashion. Be cautious of the roof falling on you and or pinching body parts. I even did my door molding as well. But the most important was the seals on the convertible roof and the interior. I used about a half of a bottle to do every interior portion of the seals including the trunk seals.
Best of Luck!
