2.0 Cavity preservation of sheet-metal parts: Notes
WARNING: This page is about a different car, the 2013 BMW 550i GT, 2012 BMW 550i GT, 2011 BMW 550i GT, and 2010 BMW 550i GT. However, it is still accessible from the selected car via links, so may be relevant.
Carry out cavity preservation after all body repairs.
Concluding cavity preservation is the most important part of all corrosion protection measures.
Use the cavity protection spray only for smaller-scale straightening work where the parts in question are easily accessible. Use the Vaupel PRESSURE CUP GUN for all other repairs. Cavity protection agent is available in different container sizes.
Use the relevant probes with tubes for the different cavity areas.
IMPORTANT:
Incorrectly performed cavity protection can, especially in the case of steel/aluminum joints, give rise to a non-calculable product liability and safety risk.
The best repair is worth nothing if the subsequent cavity protection measures are not conscientiously carried out.
