I'll have to remember to take a photo or two tomorrow, but I've had good luck with the fins and vacuum bagging with just a standard food saver. First couple of attempts have had excess epoxy, however I've found that bleeder cloth as well as release cloth seem to work wonders and I have little if any extra epoxy getting on the backside of the fins.
I also plan on putting a layer of fiberglass over the leading and trailing edges. I was trying to figure out how to get the fiberglass to fold and lay down without a struggle, same with release cloth. Then it dawned on me... heat! Why not just use an older iron and not on too high of heat setting (using polyester setting) iron a crease into the fiberglass cloth and release cloth. Sure enough, it works... got a nice crease, so now the cloths can just drape over the leading/trailing edge and get vacuum bagged!
