: As progress continues on my Tern 14, I glassed the hull last night. I cut and
: overlapped the glass as per the pygmy instructions so that the material
: would wrap around the steep angle of the hull. Now the end of the glass is
: visible on one side of the boat where I folded it over and wetted it out
: (The other side was wetted out underneath and is not visible). As is,
: there is now an unsightly spot where you can visibly see the end of
: fiberglass cloth. Will successive fill coats blend this in? Or will the
: sanding process 'ease' the transition? I am afraid that I read the
: directions wrong, but I seem to have done what they ask!
: Anythoughts?

If the glass is white, it means that there is an air gap between the two pieces of epoxy. Addig extra epoxy to the surface will not solve this problem. You have to peel back that flap of glass, add epoxy "under" it and then lay the glass back in place. You can also cut through the glass layer, and using a fine tipped syringe, fill the air gap with epoxy. As it starts to set and becomes tacky, you can squeegie some of it out. The goal is to get epoxy on both sides/through the glass.

This whole process would be rather icky.

If the glass is not white, but the problem is that you can see the ends of the overlayed glass, you can take a deep breath and relax. You just have to "feather" the glass by sanding it. The idea is to create a smooth transition from one layer of glass to the other. Once the area has been feathered, add your next coat of epoxy. As you add extra epoxy to "fill in the weave" the feathered area will become almost unnoticable.

Remember not to sand through the first layer of glass as you are doing the feathering...
