The black art to this task (pun un-intended) is this… you can’t see the exterior while you are working on it. We don’t use exterior gel-coats on AGB boats; we use pigmented resins to produce our deep, through-the-cloth colors. The resin soaks through the cloth and obtains its glossy finish from the highly-polished surface of the mold. This is called the ‘skin coat process.’
While this is a black boat, once the two layers of Kevlar have been added to the skin coat, the boat appears yellow. The interior will now be painted with a tan-colored gel coat.
