Hi folks ; I've just removed 6 decorative aluminum shutters for painting and found a few dozen wasp nests behind - some nests were old ; some were active < 1 sting > The 2 lower shutters were against brick - with a few nests ; the 4 upper smaller shutters were against vinyl "clapboard"
5 inch .. with many nests . Is there any product to seal the back of these shutters from wasps ? I hesitate to use caulk - it " welds " the flimsy shutters to the flimsy siding ... John T.
