I'm planning my first glass/foam build, seems vacuum bagging (especially wing skins) is very popular and I'd like to try it.
Can someone please point me to a link or something about what to buy, where to buy, basic instructions?
Thank You in advance.

Guys, thanks for quick reply. Exactly what I was looking for.

Here are a couple of other very good links. The first is to Jim Young's excellent video (he is a true expert in the area of foam cutting and vacuum bagging) and the second is to a very good source of vacuum bagging equipment - all you need for a very good price.
