Seat Leon >> Underbody sealant

The underside of the vehicle is coated to protect it from corrosion and damage.

The protective coating could be damaged when driving. We recommend that the protective coating under the body and on the running gear should be checked, and reinstated if necessary, before and after the winter season.

We recommend that repair work and additional anti-corrosion work is carried out by your Authorised Service Centre.


Do not apply underseal or anti-corrosion coatings to the exhaust pipes, catalytic converter or the heat shields on the exhaust system. The heat of the exhaust system or the engine could cause them to ignite! This is a fire hazard.
