Simple to use, fits standard skeleton guns, cures in 48 hours. I am doing the complete new deck of my own boat which is in Pitch Pine. The covering boards and around the tops of the frames which come up through are already done as with capping the bulwarks I would have been unable to get at the caulking seams.

The product is much softer than others and it is easy to gun in.Shelf life is 18 months !!

Sold in 305ml cartridges or 592ml Sausage (requires gun - see accessories)
