Is someone working here in a car paint shop by chance? I have clear varnish (metallic paint) on the roof and on the front bumper and are looking for a solution to seal the still relatively small places permanently……Clear varnish pen from Volvo and BMW-Clear varnish from a spray can have held exactly half a year And as soon as the places are free again, rain/frost and dirt ensure that the places slowly become larger again. True it is that one uses in professional workshops 2K-Lak. Can one with it also small places permanently seal. It does not have to be nice, only durable. Now is unfortunately too dark to make pictures… The largest place is about 3×4 cm.
