A process of making a polyester coated article is provided. The process comprises coating an article with a polyester composition to produce the polyester coated article; wherein the polyester composition comprises a) at least one rigid polyester; b) at least one polyester elastomer; c) at least one primary antioxidant; d) at least one secondary antioxidant; and e) at least one chain extending additive; wherein the composition has a enthalpy of melting of 3 cal/gm or less. L'invention concerne un procédé de fabrication d'un article revêtu de polyester. Le procédé consiste en revêtir un article avec une composition de polyester pour produire l'article revêtu de polyester ; la composition de polyester comprenant a) au moins un polyester rigide ; b) au moins un élastomère de polyester ; c) au moins un antioxydant primaire ; d) au moins un antioxydant secondaire ; et e) au moins un additif d'extension de chaîne ; la composition ayant une enthalpie de fusion inférieure ou égale à 3 cal/gm.
