Yesterday I glassed and wetted out the hull of my auk. Today I used a foam roller and added a fill coat. I don't have any drips, but it's obvious that some places have more resin than others. It mostly looks like the weave is filled, but visible if viewed from the side. From the top or straight ahead the weave does not show. A few spots shine and no weave is seen. I also have what looks like tiny air bubbles on the surface. Should I be adding another fill coat at this point, or should I let the resin set, and then do a light sanding?
