Hello, my first post in this forum. Therefore, a small introduction in advance: About 20 years ago I restored a VW beetle together with my father (KFZ master). Completely disassembled, repaired the body, installed a Dannert-Speedster kit, finished the painting work and built everything together again. In addition to the VW Beetle, I bought a Opel Monza some time ago. Both cars are now subject to extensive restorations, with as much as m My first problem: at the driver’s door a spaced place has been solved. When the car was built up (approx. in 2000) we filled the horizontal bead below the windows with (fiber) spatula. At the thickest point we applied about 10 mm. Directly on the upper hinge the mass of the spatula has now dissolved from the metal on an area of about 5 x 10 cm. In this area I removed the spatula mass from the metal. How do I build the material now best that it is a) stable and b) not rusty? I thought of a splinter set, as with this larger thickness are possible than with spatula. Many greetings, Björn
