You could just cover it in waxed demin and call it a day.
If I did that, I'd be lying in the thread title, and we can't have that!
I may look into that for the future...
Anyway, now we finally get to the fun stuff: Yay fiberglass! With any luck, I'm all set to take care of bidness:
Right off the bat I'm wondering if I sprung for enough fiberglass, but we'll cross that bridge soon enough. Handling the resin is easy enough, I just pour a little resin into the party cups and weigh it on my pocket scale; divide the grams of resin by two and add that many drops of hardener (close enough to the recommended 15 drops/oz). I started off with the idea that I would use strips of fiberglass to define how I want the final sheets to behave, I found that it is too difficult to get an even tension between both sides, causing the strips to rotate. Instead I'm going to lay down the first layer much closer to how I set up the frame: start at one place and use simple shapes to build the final product in as few pieces as manageable.
Thus far, I've learned that wax paper is awesome for this, and you can never have enough clips to anchor the fiberglass: I have 32 and even that is slowing me down (I've used 29 in the pic on the right). I've found that I'm using a lot of resin, since it builds up a little, so I'm trying a new approach to cutting back. You can see how I'm staggering where I put the resin on the first layer while I affix it to the frame, as well as the lack of resin everywhere else. I think this will help the bulk and top layers be stronger.
