ABSTRACT:
Blisters on cured molded thermoset fiberglass reinforced plastic (FRP) parts are repaired by injecting an anaerobic sealant into the blister, pressing the filled blister to reduce the blister to the preblister form while eliminating excess sealant, and heating to cure and set the sealant to hold the blister in its reduced form.
