How to keep you door seals water tight

There are a couple products that I would recommend to keep the rubber seal around the doors, top, trunk, and hood water tight. As a Z3 owner I have a little experience with it. So as preventive care I apply it to the Z4 every other car wash or so. If the seals has a tear or is misplaces it will not, of course, make it water tight, but it does a damn good job in keeping them elastic and crack-proof and avoids them to shrink over time.

The first one is called Gummi Pflege. BMW originally made it and recommend it to their service department as first things to do if a Z3 was coming in complaining about water leaks. I bought mine on Bavarian Autosport: just search for Gummi-Pflege or ask one of the sales reps about it.

The other product I was recently recommended is from Dow Corning and is called "Dow Corning 4 Electrical Insulating Compound". The interesting thing about it is that you can request a free sample.
 
I'd hate to be in their 'samples' department n the morning.... :rofl:

Sounds like good stuff though and worthy of note for when it happens.
 
I bought Gummi Pflege from dealer 6 years ago when I had problems with window seals on my 3 series, due to tree sap. I remember at the time thhey said it was used on rag tops.

Must go and find it now..
 
Great information, and I will be requesting said free sample for my Z3. By the time I get the material I hope to have my car back from the body shop! :headbang:

She had a little "run in" with a trailer hitch when she got back from HC.

When is the poor baby due back home???
 
I've read that Gummi Pflege shouldn't be used on the Z3 and Z4 seals because ours come from a US-based supplier, rather than the German one that does the 3-series.

I just got a nice sized tube from Dow Corning and since I have no experience with this, what is the best way to apply it? I assume just a thin coating on all the seals with an applicator sponge?
 
I've used DC4 for years-- it's recommended for lubricating the oil filter gasket on air cooled aircraft motors. I've Used it on the Zs oil filter o ring as well.

It's very clean stuff-- likely cleaner than your door seals. I'd recommend using your finger to apply very sparingly.
 
Poor ROADCAR is STILL NOT HOME! I ordered new headlight kit to replace headlight the suv and trailer hitch destroyed. Well they cahrged me ont he 10th but somehow lost the order so it never got shipped. Thearle's Autowerks, where the car is being restored and perfected never told me they had not received them until this past Wednesday! I cna kind of forgive that as my project leader was dealing with his very sick mother who passed away this week. So the car is repainted, all dents, dings and many scratches magically gone, and all it needs is that missing passenger side headlight. Good news, after a really NASTY fax from the this morning and a threat to contact the State Attorney General's office and the BBB and I would have! They are shipping the lights out overnite delivery and waivilg ALL shipping charges. I hope I get the car back Tuesday. I so wanted to go on that run Sunday but not in a Nissan Altima! UGH, that is my rental!

When I contacted the company for my free sample, completed the on line form, got email confirmation it was accepted and being processed. Then I got the email saying they do not mail samples to individual email addresses. Not sure what the heck that means other than I am NOT getting the sample. So do I need to combine my address with someone elses? I even used my business name and they still would not honor request for free sample. So it is not free to me, must just be me!

I ran into that same problem so I just used my work email and work address and they sent it to me UPS Ground. Not bad, a nice 150g tube for free!
