Novel liquid crystal polymer coatings and methods of applying the same. The liquid crystal polymers (LCPs) comprise high-melting point thermal plastics selected from the group consisting of co-polyesters, co-polyesteramides, or multiple monomer wholly aromatic polyesters. In the preferred embodiment, the LCPs may be chemically modified to provide greater hardness. The method of the present invention involves the thermal spraying of an LCP on the tooling used for curing composite structures.
