Abstract

See full text

A method of sealing surface imperfections on a sanded surface of a repair to a vehicle body is provided that includes an uncured layer of a formulation being applied to sanded cured body filler on the vehicle body. The formulation includes a polyester resin, a crosslinking agent, a solvent, and a particulate filler. The uncured layer is exposed to actinic radiation to induce cure of the uncured layer to form a sealing coating. The resulting seal coating has able to seal surface imperfections. A surface imperfection sealing formulation is also provided that includes a polyester resin and a multifunctional crosslinking agent. A solvent is provided. A photoinitiator renders the formulation curable upon exposure to ultraviolet light exposure. A particulate filler is also present in an amount to result in a formulation with an uncured viscosity of between 2600 and 3000 centipoises.
