The present invention relates to a method of making a multi-coat coating comprising the steps of: i) applying a primer-coated substrate (I) to an optionally pretreated substrate, ii) curing the primer-surfacer coat (I) iii) applying a basecoat (II) to the cured primer-finisher coat (I) iv) optionally curing the base coat (II) v) applying a clearcoat (III) to the cured or uncured base coat (II), and vi) curing the base coat and the clear coat when the base coat is not cured in clear coat (III) or step iv) The primer-coated film coat (I) is characterized by being obtained by applying a non-aqueous, solvent-based coating material (F) comprising At least one organic solvent in an amount of at least 20% by weight based on the total coating material (F) A1) at least one first polyester (A1) having a glass transition temperature of 20 DEG C or higher and an acid value of 0 to 40 mg KOH / g, based on the total coating material (F), of at least 8 wt% A2) at least one second polyester (A2) which is at least 8% by weight, based on the total coating material (F), a glass transition temperature different from (A1) B) one or more crosslinking agents (B), and C) at least 8% by weight, based on the total coating material (F), of at least one filler and / or pigment (C). The invention also relates to a multilayer coating which can be obtained according to the process and a substrate coated with the multilayer coating. |
