Water Based Silicone OK?

BluesDriver · 02-16-2012, 03:00 PM

Looking at the manual it says to not use any silicon based products on the rubber seals.

I was looking at the Einszett gummi pflege and this contains water based silicon. After asking Einszett about this I got the following response:

Thanks for your question about Gummi Pflege and sorry for the confusion. Gummi Pflege contains a water based silicone. What it doesn't contain is silicone oil in a petrol solvent emulsion which can dry rubber and cause it to fail (ie tearing/cracking) down the road. Water-based silicone in a water based emulsion is in no way harmful. Silicone offers water resistance and helps repel dust.

So, is there any harm in using this product even though it has a form of silicon in it?

I have used it for years and it works great. I don't think I have ever heard anyone say anything bad about it.

It works great. It lasts a long time and completely eliminated the flex squeaks in my door seals and sunroof.

I recommend shin-etsu rubber grease. can buy at Honda dealership. in my opinion it works better then Gummi, but takes longer to apply

I use Gummi Pflege or a rubber conditioner. Apparently people get great results with WD-40 but I don't know about using that.

Gummi. I've used it for a decade+ on multiple BMWs. Never an issue.
