ABSTRACT:
A method for selecting a formulation for one or more layers of a multi-layer coating for repair purposes, the multi-layer coating comprising a primer applied on a substrate, at least one base or top coat and, optionally, a clear coat, the method comprising the following steps:providing a database of colorimetric data relating to a set of formulations and/or relating to constituents for a primer and preferably for one or more base or top coat layers for a multi-layer coating;entering the colorimetric data of an object to be repaired into a computer having access to said database;determining the formulation of the primer and, optionally, of one or more base or top coat layers with the aid of the database, in such a way that the resulting color of the multi-layer coating to be applied matches the color of the object to be repaired using the lowest possible amount of coating material.
