501-36-17 Paint - General Information 501-36-17 DESCRIPTION AND OPERATION TO BE UPDATED LATER Repair of damage: ‡ Wash immediately if the contamination is fresh. ‡ If the contamination has dried on, dissolve and neutralise it with vinegar, then thoroughly wash off with water and rinse. ‡ Rectify mild damage using a polishing repair. Rust film/deposits from industrial fallout Small round marks, about 1 mm in size, in all shades from black, grey, blue to reddish, on the horizontal surfaces of the vehicle. Cause/damage pattern: ‡ Deposits from oil fired systems and industrial plant, especially at high humidities and inversion weather conditions, cause damage to the paint top coat. ‡ As the activity time increases so called rust halos form. They spread as long as the deposits corrode. ‡ Industrial fallout containing iron will no longer be removable after a few days! TO BE UPDATED LATER Repair of damage: ‡ Remove the dust using an industrial fallout remover and thoroughly wash. ‡ Polish the paint surface. NOTE: Never try to remove the particles of industrial fallout by polishing or rubbing! ‡ Use cleaning dough. Damage caused by battery acid. Splashes of battery acid caused by carelessly topping up the battery. WARNING: Batteries contain sulphuric acid. When working near the battery, or where there is battery acid on the vehicle body, protect the skin and eyes from contact with the acid. If battery acid contacts the skin or enters the eyes, flush the affected area immediately with water (flush for at least 15 minutes) and call a doctor without delay. If acid is swallowed, call a doctor immediately. Failure to follow these instructions may result in personal injury. NOTE: High temperatures accelerate the attack on the top coat. At 50°C the top coat layer breaks down after about 15 minutes! Cause/damage pattern: ‡ Etching of the paint layer to decomposition of the paint finish. TO BE UPDATED LATER Repair of damage: ‡ Flush the acid splashes with plenty of water and neutralize with car washing liquid. ‡ If the contact time of the acid was short, perform a polishing repair. Paint damage caused by brake fluid. Careless handling of brake fluid. The glycols contained in the fluid cause swellings.
