Abstract: The composition includes at least one of a dicyclopentadiene-modified unsaturated polyester resin or an ethylene glycol fumarate unsaturated polyester resin; a vinyl ester represented by formula R—[C(O)—O—CH?CH2]n wherein R is alkyl, aryl, or a combination thereof, and n is 1 or 2; a tertiary amine; and inorganic filler. A method of repairing a damaged surface using the composition C is also described.

Abstract: The composition includes a polyester resin comprising at least one ?,?-unsaturated ester group, an acrylate or methacrylate, a vinyl ester represented by formula R—[C(O)—O—CH—CH2]n, wherein R is alkyl, aryl, or a combination thereof and n is 1 or 2, and a metal salt of a carboxylic acid. A method of repairing a damaged surface using the composition is also described.

Abstract: The composition includes a polythiol having more than one thiol group and an allylic resin having more than one allyl group. The composition typically includes inorganic filler. Typically, at least one of the polythiol or the allylic resin has more than two thiol or allyl groups, respectively. A two-part body repair composition including the composition and use of the composition as a body repair composition are also disclosed. Methods of repairing a damaged surface are also disclosed. The method can include combining a composition with at least one of an organic peroxide or hydroperoxide, applying the composition including at least one of the organic peroxide or the organic hydroperoxide to the damaged surface, and curing the composition on the damaged surface to provide a cured composition. The composition includes a polythiol having more than one thiol group, an allylic compound having more than one allyl group, and inorganic filler.
