Not intended for eternity

Underbody protection on bitumen base has long been regarded as a poor choice when it comes to preserving the basement of the body permanently against corrosion. The means of Liqui Moly is applied from a half-liter spray and is good so at least for the quick coating in between.

The tar-like substance that sticks well to the plate and cover with a black film everything that could possibly draw the suspicion of TÜV engineers in coming. Since the auditors are familiar with such deception, a freshly sprayed bitumen Underbody protection is virtually always excited her suspicions, according to the motto: Here someone has something to hide. For indeed often holding the viscous mass prepared surprises. Even for the car owners who wonder why the sound-sensitive protective layer dissolves at some point in large Placken and including either rusty tin or holes appear. Of all the types of underbody protection agents on bitumen basis have the greatest risk to be rust despite an apparently intact surface if water somewhere passes through a leak to the plate. In addition, such underbody protection tends per se to the formation of fine cracks, which the fate takes its course. The good resistance to external influences such as stone chips and abrasion does not help in these circumstances. The spray is ideally processed at room temperature. On vehicle it holds up to 100 degrees; a statement which is relevant for use in the exhaust area. If the product gets good reviews, then for its good coverage and easy application. From the actual purpose of the agent, a good long-term protection, there is no mention. Probably because of this criterion can be assessed only over long periods. Still less are the chances of successful work, if the spray is used on a non carefully derusted underground, since the corrosion starts soon. In order to improve the anticorrosive properties of the underbody protection should not be applied to the bare metal. An anti-corrosive primer as a primer is recommended.

Viewed objectively, the field of application of bitumen Underbody protection is very limited. It is used to coat the bottom plate or wheel arches with little effort so that rust is not a short time reappears and welded sheets are somewhat protected and concealed. For pending TÜV appointments or selling date of an ailing used car, it is useful for long-lasting body repairs not. The 500-milliliter spray provides for Amazon to 6.39 EUR.
