Mine isn't perfect, but much better than most i've seen.

This makes perfect sense and I wish I had thought of rounding the edges before I got this far.
Thank-you for your help!

you can use some cabosil filler to make "inside" turns easier. fill corner with thickened resin, apply mat in area while filler resin is still wet working air out as you go.

hope this helps

Thank-you, we have tried this and it is working much better.

Thanks,

I have a 74 Vector and I am doing a full restore. I am attempting to fiberglass my stringers or beams in and the fiberglass cloth is enveloping the beam with the cloth being fiber-glassed to the floor of the boat up the side of the beam or stringer and over the top and down the other side and attached to the bottom of the boat on the other side. The problem I'm having Is that no matter how hard I try I can't get the air out of the top of the cloth or the top of the stringer. Air bubbles appear on the top and overlap to the sides, almost a mushroom effect. Is this a problem? What should I be doing? I really need your help as I don't want to mess this up. I remember when I tore the core and beams out that it had this same mushrooming effect but maybe whoever did it in the past was making the same mistake I am. I could cut out or grind out these bubbles and redo but, what does everyone else do?

Thanks,
