PVC corrosion protection measures - PVC underseal
/ PVC protection from chippings
The areas that are susceptible to damage from chippings are
specially coated with PVC underseal. The aim of this is to achieve
permanent protection.
PVC underseal is applied on top of the priming.

Body sealing plug and cover
Sealing plug
Some of the sealing plugs used to close up openings in the body
are secured with a hot-melt adhesive.
The adhesive has already been applied to the new part.
A sealing plug with hot-melt adhesive is removed by supplying
heat with a hot air blower
Heat up the body area around the plug evenly until the adhesive
melts and the sealing plug can be removed.
Use a new component for installation
When installing make sure that the area where the hot-melt
adhesive must adhere is free from impurities and residues of
adhesive.
Before inserting a plug, heat the surrounding area of the body
uniformly (to approx. 120°C). Then insert the sealing plug and
push it on. The hot-melt adhesive runs and seals the area.
Afterwards, briefly heat the inserted sealing plug with the hot air
blower (mad.0.5 min).
