[WBMZeos]

I’m new to having an Eos and extremely happy with the car but from what I have been reading I’m also a bit worried about all the repairs. So I’m trying to keep ahead of huge possible bills.
One easy maintenance issue is the lube for the roof. I’m in the United States and I’m trying to find the right version of Krytox and where to get it. Any help would be appreciated!!

Also, all you pros out there other than the timing chain(belt?) that needs changed what do you do to keep the car running smoothly!!

Thanks guys and ladies for all your help!!

Many people on this site recommend the Krytox, but I recommend that you try Gummi Pflege Stift, a slightly cheaper chemical that is recommended for hardtop convertibles in both the Mercedes Benz and the BMW lines. I have used this on my Eos since I got it after using it on my Mercedes SLK280, and I have never had a drop of water enter the cockpit even in the midst of torrential rainstorms common here in coastal Florida. I believe that others posting here have also had good luck with it.

Mercedes recommends Krytox, not Gummi Pflege. I have a bottle of Gummi Pflege, but use it on other rubber trim, not the top trim

I use Krytox for the roof and Gummi Pflege for the door and boot seals.

I use Gummi Pflege Stift for all roof seals....... has worked very well, no leaks......for the doors / boot etc I use Gummi Pflege Liquid Molly 1538 which comes in a much bigger bottle .........the VW Krytox seems insanely overpriced

I take it you have not used Krytox yet.

All it needs is a tiny drop on your fingertip, and you massage it in. Goes a long long way.
(It is a really thin oil, a bit like sunflower oil)
Trust me. I was in the same boat as you about the cost when I got my EOS, but at the end of the day, once your seals are done, they are done.

No going back.

How long have you had your EOS and been just using Gummi?
If it's a short while, how do you know it's protecting those seals?

Also depends if you have it in a garage or out in the elements.
Next year you could end up with more leaks than in a Welshman's allotment.

For around £15 you will have enough for 18 months. (20p a week)
A very small price to pay compared to the alternative.

No i never have....my car is on the road, and has been for 3 years..... for £15 I will give Krytox a go, the VW stuff is £68 for 30ml online...

According to the owner's manual that came with my 2006 SLK280, that is an incorrect statement. Krytox is not even mentioned anywhere in the manual. Perhaps that has changed recently, if that is so I would not be aware of it. I never heard of Krytox until I started reading this website.

FWIW, Krytox is an expensive flourine based inert industrial lubricant originally sold by Dupont. It's also used to lubricate dive equipment because it has no reaction with Oxygen gas. Krytox was never designed specifically for use on convertible rubber seals, it was probably the best and only solution available at the time.

Because Krytox wasn't designed specifically as a lubricant for car roofs, it contains no U.V inhibitor additives which Gummi does. I have a large bottle of Krytox, but I've also use Gummi and occasionally high factor sun lotion. The name Krytox sticks because it's unique, but it's not surprising that alternative products like Gummi are now available. Lubricating roof seals is better than doing nothing at all and if somebody hasn't the money to spend on Krytox and uses Gummi, at least they are doing seal maintenance.

I've seen some surface degradation on MY07 seals, but about what I would expect for age and there are no leaks I haven't fixed. Most EOS roof seals seal by contact pressure. They are a quite fragile foam rubber and it's important they are kept pliable and don't shrink back or distort. Watching seals dry out, wash out and surface harden during Summer then having to re-lube, I think U.V is an often overlooked contributor to reduced seal life? I would expect this to be an important factor in the sun States.

Merc. & BMW roofs don't leak because they are a simpler better quality design. You can't say because Krytox works for them, your EOS roof won't leak!

I've been using Gumry to use it twice a year.mi Pflege on my '07 for the four years I have had it and it works fine. I try to use it twice a year. With respect to UV, it is ubiquitous (except maybe Eire and England). Heat in hot climes will also cook seals.

I admit it- I do live in a hot climate, and the Mercedes that I owned was sold in West Palm Beach, so it may be that Mercedes was aware of the UV properties of Gummi Pflege and recommended its use in cars sold in hot climates, at least up until 2006. That is the reason I have used that chemical exclusively on both of my hardtop convertibles, and my EOS has never leaked even one drop in the massive rainstorms of the monsoon season here in Florida. Given that success, I see no reason to use anything else, certainly not a more expensive chemical.
