factory undercoating

[feelstranger]

Hello,
I am looking into re-doing some undercoating on the 200 and a VW syncro vanagon.  I was wondering if anyone here know if the factory undercoat on the 200 was one of the products made by Wurth?  The Vanagon has a more waxy type undercoat that I believe may also be from Wurth.
I may go with the Waxoyl hardwax for both but figured If I can get OEM for the 200 I would. 
 What do you know?
BTW - if you don't know about Wurth, they sell all kinds of things that are OEM To European autos - check out the web site (Wurthusa.com)  I just would like to see prices on line!
