A self-forming sealant system forms a seal between two parts or between a fastener and a part of a structure. In forming the seal, a first finish (50) having a high surface energy is applied to the joint between the two parts or is applied to the fastener and the part. A second finish (60) having a low surface energy is then applied adjacent to the area where the first finish was applied. A sealant (66) is then applied to the joint between the two parts or the fastener and the part, where the sealant migrates to the joint or fastener coated with the first finish having the high surface energy and away from the areas adjacent the joint or the fastener coated by the second finish having the low surface energy. |
