A double coating, curing method, cured coating, and kit are provided. A first layer of the double coating can be a first cure coating composition, which has a first hydroxy-functional resin, a first crosslinking agent, and a first catalyst. A second layer of a second cure coating composition can have a low hydrophilicity acrylic resin as a second hydroxy-functional resin, a second crosslinking agent, and a second catalyst. The first catalyst catalyzes crosslinking between the second hydroxy-functional resin and crosslinking agent, and not between the first hydroxy-functional resin and crosslinking agent. The second catalyst catalyzes crosslinking between the first hydroxy-functional resin and crosslinking agent, and not between the second hydroxy-functional resin and crosslinking agent. The first and/or second hydroxy functional resins can facilitate catalyst migration from one layer to the other. The separate compositions can be shelf-stable and/or the curing can occur at low temperature.
