An inside spray coating composition comprising:an aqueous carrier; andan emulsion-polymerized latex copolymer dispersed in the aqueous carrier, and comprising:one or more mono-unsaturated monomers each having a single ethylenically-unsaturated group; andone or more multi-unsaturated monomers each having two or more ethylenically-unsaturated groups, wherein the multi-unsaturated monomer(s) each have a divalent chain length with at least two carbon atoms between at least two of the ethylenically-unsaturated groups, and constitute from 8% by weight to 25% by weight of the monomers used to produce the emulsion-polymerized latex copolymer;wherein the coating composition preferably includes less than 1 weight percent, if any, of vegetable oils;wherein the coating composition has an average viscosity ranging from about 5 seconds to about 40 seconds, pursuant to the Viscosity Test; andwherein the coating composition has a resin solids content ranging from about 10% by weight to about 30% by weight, based on a total weight of the coating composition.
