Cut the tape to length and lay it out on a plastic sheet. Wet it with epoxy with either a brush or a spreader, then roll it up. Unroll it in place and smash it in fillet with glove and smooth with spreader , gloved hand, brush, whatever works best in that spot, It is a real benefit inside at the where the floor joins the sides and transom area. It really is easier than it sounds and believe it or not it isn’t messy.
