impregnating a fibrous support with an uncured formulation comprising: a polyester resin, a crosslinking agent, a solvent, and a particulate filler, the uncured formulation having a viscosity sufficient to impregnate the fibrous support while also being retained on the fibrous support to form a matrix surrounding the fibrous support;
contacting the fibrous support with the surface defect;
placing an article into the surface defect to underlie the fibrous support prior to the contacting; and
exposing the uncured formulation to actinic radiation to induce cure of the formulation to form the patch to repair the surface defect.
