Slick Seam is an excellent underwater seam compound for wooden boats. Requires no mixing, stirring or priming. Made of wax, pure mineral products and silicate fibers, Slick Seam adheres well to most solid surfaces whether dry, wet or even oil stained. Applies easily and cleans up fast with mineral spirits. Cures ready for paint in 30 minutes. Stands up well to flexing and swelling wood. One jar is enough to caulk the seams on most boats to 20'.
