Made from balsa resin, beech tar, wax and linseed oil and used to impregnate and seal underwater leaks and cracks in planking by swelling with water. Very useful on board any wooden boat especially leaky or dried out; works on clinker boats too. It’s only to be used below the waterline however. You don’t want it all over the place. £12 for 230ml tin or £37 for 1000ml
