My preference is Elring's Curil(tm) Products, the original stuff VW
used to assemble in the 1st place.  I've used the product(s) to
assemble aircooled engines (Type 1 and Type 4 in the past with
excellent results thanks to the guidance of an experienced VW Factory
mechanic a few decades ago. Whether they are applicable to the
Wasserboxer, I can't say because I've never assembled one.  But I can
find out.

There are 3 different compounds for specific uses.  I'm not in
position at the moment to elaborate, but tomorrow when I'm in the
office, I will update when I have the reference materials at hand.
