Applying filler
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 BMW 760Li, 2014 BMW 760Li, 2013 BMW 760Li, 2012 BMW 760Li, and 2011 BMW 760Li. However, it is still accessible from the selected car via links, so may be relevant.
Apply pressure to apply a thin layer of metal filler. Carefully coat all edges in gaps with filler.
Then fill gap completely with filler. Apply filler with about 30% excess because the filler will significantly shrink during hardening. A second application of metal filler is not possible due to poor adhesion.
IMPORTANT:
Use a narrow spatula to fill the gaps. Apply the filler in one draw if possible. Danger of formation of pores in gaps!
No restrictions related to the layer thickness.
