Coating composition

A method for healing a coated substrate comprising the steps of:

• selecting a coated substrate comprising:
• a substrate;
• a coating layer associated with said substrate, wherein said coating layer comprises a film, wherein said film is derived from a coating composition comprising the reaction product of:
• (a) one or more natural oil derived polyols having an average of 3 or more hydroxyl groups per molecule, a number average molecular weight in the range of 300 to 3000, a Tg in the range of from less than 0° C.;
• (b) one or more polyisocyanates;
• heat treating said coating layer at a temperature in the range of from 10 to 90° C.;
• thereby healing said coated substrate.
