The wax products Multiwax and Hohlraumversiegelung HV-200 and HV-400 are well known to me, so I slammed with enthusiasm, as a larger amount of this product were in a certain auction house. I have thus treated the underbody of the car of a former good friend. Since I am working intensively with rust, I think I have this rustproofing carried out correctly, the product was therefore not sprayed onto existing rust nests, water, dirt. Was used a Vaupel pressure spray gun. After only a winter product no trace of was even in warm temperatures very brittle and could easily be blown off with a screwdriver, "always flexible, self-healing, like small damage on its own from". I can only advise against this product. My former good friend I had to marry as compensation :-)
