It is best to mask off the edges with adhesive paper beforehand. Apply sparingly with the SONAX P-Ball or the SONAX Application Sponge to the cleaned and dry surface and rub in intensively for several minutes. Then, remove the residues with a microfibre cloth (e. g. SONAX Microfibre Cloth Exterior). Repeat application for deep scratches. Sand individual very deep scratches beforehand with sandpaper (5000 grit) and a little water. Do not use on printed, soft, or coated plastic surfaces.
PLEASE NOTE: Protect against frost.
