Hi Listers,  The factory (wax) undercoating has worn away (to the
paint) in the wheel wells.  Time to reapply & keep the rust away.  Is
the factory wax stuff available at FLAPS or is this VW dealer
only?   Has anyone ever bought some from a VW dealer?  Is it in spray
cans or brush-on?  I'm leary of using the tar based spray-ons due to
any incompatibilities with the wax.  Others on the list speak of
Koolpatch brush-on undercoatings.  What color is this material?
Thanks for your help.
