Polyester molding compositions are produced which exhibit a good balance of properties such as flow into molds, gloss and other surface characteristics of molded parts such that they generally do not require painting prior to use. Such are particularly useful for molded parts for consumer and industrial applications. The composition contains a thermoplastic polyester polymer, a reinforcing component, a plasticizer, and a mixture of nucleating agents. A first nucleating agent is an alkali metal salt of a carboxylic acid in an amount of about 0.15 to about 0.35 percent by weight and a second nucleating agent is a metal salt ionomer at from about 0.35 to about 1.2 percent by weight.
