Yesterday, I glassed my first airframe section in 14 years, and I didn't do as well as I had hoped.
I used a 4" light sock from Soller Composites on a section of 4" PML airframe, applied epoxy, then applied a teflon release followed by a breather layer, then placed the entire section into a foodsaver bag and vacuumed it down.
At the time, I thought I had maybe used a little too much epoxy, but after I removed it from the bag and peeled off the teflon and breather this morning, there are areas where it looks like the epoxy was insufficient. I also noticed that there are a several areas where I had bubbles, and it looks like I had a few wrinkles in the teflon. I had the sock completely smoothed out prior to applying the release, and the again prior to wrapping the breather on it. The following photos show after I sanded it down.
So, my question is, is it salvageable? I was an idiot and used the slotted section first, and so it will not be as cheap to replace. I am tempted to sand it more, then apply a second layer of the sock over it and carry one, but I am not too sure. My other choice is to go with option B and purchase some FG tubing from Madcow or similar and call it good.
