Liquid or aerosol jet coating compositions for substrates, coated substrates and methods of coating

A method of coating a coil substrate, the method comprising:

• directing a liquid jet or aerosol jet coating composition to at least a portion of the coil substrate, the liquid jet or aerosol jet coating composition comprising:
• polymer particles comprising a polymer having a number average molecular weight of at least 2000 Daltons, wherein the polymer particles have a particle size distribution having a D50 of less than 10 microns;
• and
• a liquid carrier comprising water in a major amount of the liquid carrier;
• and
• providing conditions effective for the liquid jet or aerosol jet coating composition to form a hardened continuous adherent coating on at least a portion of the coil substrate.
