Can TotalBoat TotalFair be used over a 1-part paint?

It is not recommended to apply TotalBoat TotalFair over 1-part paints. Fairing with epoxy products should not be performed over any 1-part paints. TotalFair will not have the same bond strength with a 1-part coating compared with fiberglass, wood, metal, or other 2-part epoxy materials. As a convention, all fairing should be done before applying any topside paints to ensure the best bond with the substrate. In addition, TotalFair will likely not sand at the same rate as the 1-part paints, which could complicate the process of fairing by adding extra steps, labor to complete the fairing job, or material required.
