Abstract
A process for producing a repair coating on at least one metallic surface that is coated with at least one corrosion protecting coating A, applied from at least one composition selected from the group consisting of pretreatment compositions, organic compositions and silicon compound containing compositions; wherein the at least one corrosion protecting coating A has been at least partially removed in an area Z, and a thin corrosion protecting coating B, containing at least one silicon compound, is applied, from a composition that is a solution or dispersion containing at least one silane, silanol, siloxane, polysiloxane, or any mixture of these, on at least a part of the area Z. Optionally, a further corrosion protecting coating C may be applied on the thin corrosion protecting coating B whereby the at least one further corrosion protecting coating C is applied from at least one organic composition such as, for example, a primer, a wet-primer, an e-coat, a powder coat, a base-coat or a clear-coat, or with at least one composition which is the same composition as or a different composition than that which the thin corrosion protecting coating B is applied.
