EndCuts ($9.99 for a 4-ounce bottle) seals and protects the ends of siding and trim from water penetration. It works on all types of lumber to help ensure that warranties (which typically depend on whether end cuts are sealed) are not voided. The environmentally friendly water-base formula comes with a sponge applicator and can be used for interior and exterior applications.
