Once we are satisfied with the shape of the panel, we need to make sure that shape stays in when we release the panel from the forming templates. To insure this, we have to glass the inside of the panel at the curve of the bottom of the hull.
The first thing to do is fill all the cuts we made previously. While the forming straps remain in place, we fill with a mixture of micro balloons and resin to provide a smooth surface for the inside layers of glass.
Run your hands over the whole surface to make sure there are no large bumps of fill that would give the glass a problem and make it stand proud of the surface. It is a lot easier to sand the fill material at this point then it will be once the glass and resin is applied.
We apply two layers of 10 oz. glass cloth with resin. Stagger the layers so there are no abrupt changes in height. Make sure you get the cloth close to the inside layers of glass that cover the inside of the panel. Do not go all the way to the edge of the panel as there will be more glass added here when you put the two panel halves together. You will have to work the cloth with serrated rollers to get all the air out and to insure good bonding.
The glass is applied as close to the forming templates as possible without glassing them into the panel. The straps remain on while the glass and resin cures.
The panel is now formed, glassed and cured, ready to be taken out of the forming frames and templates.
