501-36-45 Paint - General Information 501-36-45 DESCRIPTION AND OPERATION Sand the filler. TO BE UPDATED LATER The working area is expanded by applying new masking. This makes it possible to even out the transition from the damage area to the vehicle paintwork. NOTE: The primer filler must be carefully sanded. Faults in the primer filler layer will be visible in the top coat. The sanding process consists of two stages. Coarse sanding levels out the surface of the filler primer. Fine sanding ensures the necessary surface structure which allows the top coat to adhere well and cover sanding marks. Sand the filler using the eccentric sander and P400 - P500 used dry. Clean the sanded filler finished surface using silicone remover. The painted area is matted using a fine matting sponge, and then thoroughly cleaned. Surface ready for paint TO BE UPDATED LATER The surface which has been repaired and then prepared according to the manufacturer's instructions is now ready for basic paint application. Top coat application It is important for a good paint result that the recommended process data is adhered to, i.e. mixture proportions, layer thickness, viscosity, drying time etc. First of all the work area is carefully masked ready for paint application. The correct adhesive materials and techniques must be used so that no hard transitions and edges are created during painting. NOTE: The chapter "Tips and Tricks" gives in-depth information on masking work. Thoroughly check the surface once more and rub-off with a dust-bonding cloth. NOTE: Once more check the paint material and that the spray gun is correctly adjusted before applying the paint. Paint application TO BE UPDATED LATER The base paint is applied in two or three steps. First of all only the repair area is painted with the first paint application. Flash off TO BE UPDATED LATER Allow the paint application to flash off until the surface has a matt appearance. So that the transition to the original paint is optimally created, the next paint application is applied to a wider area. After the base paint has dried for the specified time, the clear lacquer is applied. Next the transitions to the original paintwork are treated with fade-out
