What this video covers

To prepare a boat hull for painting, remove all surface texture from the primer using 320-grit sandpaper and a Festool RO 150 random orbital sander.4:48 Apply a black powder guide coat, such as the Mirka brand, to identify low spots or remaining texture; sand until the guide coat disappears completely.1:05 For dark colors like Infinity Blue, use a dark gray primer to ensure proper coverage, while light colors like Fighting Lady Yellow require a white primer.5:55

To apply Alexseal paint without the traditional "roll and tip" method, mix the paint, converter, and reducer at a 2:1:1 ratio, then add the Alexseal 5018 rolling additive.13:42 For a one-quart total mix, use 10 milliliters of the additive.14:11 When applying, use a lint-free roller, keep the paint layer thin, and avoid overworking the surface to prevent premature solvent evaporation.19:43 While the additive significantly reduces orange peel, full coverage may require multiple coats, especially if the primer was sanded through to the fiberglass.24:03
