A method of forming a gasket in situ between two components which comprises injecting into a groove in at least one of said components a curable composition comprising: one or more free-radical polymerizable vinyl esters, and ingredients of a rapid free-radical cure system therefor, the cure system being inactivated prior to injection of the composition, and the composition having a viscosity at 25°C in the range from 200 to 500,000 mPas; and permitting the composition to cure. The composition can be a two part composition wherein the first part contains a prepolymer, monomer and activator and the second part a prepolymer, monomer and activator. The composition can also comprise two expansion reactants, each in a separate part of the composition prior to injection, which react to form a gas in situ in the composition. The gasketing composition is suitable for use in engines and other machines e.g. in industrial manufacturing plants. -28-
