Spots of corrosion on top of the paint surface
Industrial Dust Corrosive deposits from chimneys of foundries and ironworks. Rail and road chippings. Iron particles, which mainly occur on top flat surfaces, oxidise in moisture and humidity and then attack the paint surfaces. Spark Damage Ash from overheated electricity cables on tramways and railways. Spark damage from welding and grinding operations. The hot and sometimes glowing, particles of iron burn into the paint surface.
Immediate removal of the metal particles and regular maintenance by polishing and waxing will help to avoid the problem. Where welding or grinding work is being carried out, ensure that all vehicles adjacent to or near the work are fully covered to protect them.
Use a metal dust remover and finish off by polishing the surface with Glasurit Fine Polishing Paste 562-1602. If the metal particles are deeply etched into the pain surface, sand down the affected areas with P1200 and then polish with Glasurit Fine Polish Paste 562-1602 and finish with any standard deep gloss polish.
