Catania wished to paint the exterior of his house. He went to Brown, a local paint store owner, and asked him to recommend a paint for the job. Catania told Brown that the exterior walls were stucco and in a chalky, powdery condition. Brown suggested Pierce’s shingle and shake paint. Brown then instructed Catania how to mix the paint and how to use a wire brush to prepare the surface. Five months later, the paint began to peel, flake, and blister. Catania brings an action against Brown. Decision?
