Claim:
A method for selecting coating formulations for 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 one or more databases of colorimetric data relating to a set of formulations and/or relating to constituents for a primer and base or top coat layers; 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 of the other layers of the multi-layer coating with the aid of the database, in such a way that the resulting colour of the total multi-layer coating to be applied matches the colour of the object to be repaired using the lowest amount of coating material by allowing the color of the lower layers to be visible and have an effect on the resulting colour.
