My Feedback: (2)

Thanks Gregg for the tips and thank you Scott for the pva offer. I did find a local that has some pva if I want to use it but he has been laying up glider parts (wings and fuses) for a while now and looked at my mold and said I did not need to use it. "Just use the wax and it will be fine" I pulled my first cowl out of the mold this morning and it turned out ok for the first one. I was only after one cowl but I think I can do better. My epoxy was old and the 3 oz cloth was so tightly weaved that I think it was hard to get all the tiny bubbles out from under it. I used two layers of 3 oz, and two layers of 6 oz. I think I might skip the gel coat next time and use two layers of .75 and then one layer of the 3 oz and then two layers of the 6 oz. . I cut all the pieces out at a 45 deg bias and I think it helped lay down better in the corners. I did have a bunch of little air bubbles between the gel coat and first layer of glass this time around. For the first layer of glass, I wetted the inside of the mold and then laid the glass in dry and then wetted it. It was not easy. I started wetting the glass first and then it laid down a lot easier.

Here are some pictures of the first pull.
