Dirt inclusions and paint runs can be removed with the sanding cylinder ("Finiball") and hand sanding or eccentric sander in a wet sanding process.
Another practical tool for removal of paint faults which lie proud of the surface is the paint plane.
NOTE: Guide the tool carefully with the minimum of force. It must not tilt, otherwise more serious damage may easily be caused.
This tool allows paint faults to be carefully removed in shavings. Afterwards the surface must be polished using suitable materials.
