A method of forming a multilayer coating on a substrate is provided. The multilayer coating exhibits reduced strike-in and mottling. The method includes the steps of providing the substrate including a primer disposed thereon, applying a basecoat composition on the primer, applying a clearcoat composition on the basecoat composition, and curing the basecoat composition and the clearcoat composition to form the multilayer coating on the substrate. The basecoat composition includes a film forming resin, a pigment, and about 5% to about 75% by weight on binder of a cyclic lactone modified branched acrylic polymer having a hydroxyl monomer content of about 1% to 65% by weight, all or part of which has been reacted with a cyclic lactone, and having a weight average molecular weight (Mw) of about 10,000 to about 150,000 g/mol.
