Can be used anywhere in blended painting with clear paint and finish paint. With its special formula it dissolves the edge zones, creating a very fine distribution of paint in the transition zone. This means considerably less polishing. Ideal for spot repairs. Immediately after application, apply DUPLI-COLOR 2K Super clear paint, 2-coat clear paint, DUPLI-COLOR Auto Spray or DUPLI-COLOR Auto-Color on the transition zone in the blender area.
