6 oz woven fiberglass tape.
Fiberglass cloth tape is made of twisted strands of fiberglass that are woven at right angles to one another. Woven cloth has the highest glass-to-resin ratio and strength of all fiberglass materials.
Fiberglass tape is usually a narrow, cloth strip with woven edges that prevent unraveling.
Use this tape for reinforcing seams and corners, and over epoxy fillets on plywood stitch and glue boats.
