Abstract
In a process for overcoating a substrate having a cured primer coating with a curable topcoat which when cured is swellable by a stripping solvent, a non-volatile polar material is applied to the primed substrate from an aqueous liquid vehicle before coating with the topcoat. The polar material facilitates the removal of the topcoat from the primer by the stripping solvent, as is required for example when repainting aircraft. The polar material has sufficiently high affinity for the primer surface that it is not washed off the primer surface by water rinsing or by application of the topcoat paint.
