Autoglym Liquid Clay / Magma
https://www.meticulous.guru Iron contamination bonds to your vehicles paintwork and wheels over time. Initially it may look like little black specks on your vehicles paintwork. Unlike tar these little specks eventually corrode, turning brown. It's particularly noticeable on white cars but will dull the finish of all colours. If left untreated iron contamination could cause the failure of your vehicles paint system. Removal is easy and safe. Meticulous.Guru uses Autoglym's Liquid Clay Fallout & Iron Remover for this task. Available on selected services.
