I've always used 1-mil plastic "drop cloth" from the local hardware store.  I tried different thicknesses and the 1-mil seemed to work the best.  Very cheap and works just fine.

Fellow Builders, For the past several years of building my Legacy, I have been purchasing the blue plastic release film, used for wetting out multi-bid layups at the same time, from Lancair.  A few weeks ago, Lancair said they were completely out of it, and no longer had a source for it.  My own research has not resulted in finding a source either. Anybody know where I can purchase it?  Has anyone completed their project and still have a bunch of the plastic film on the roll? In the interim, I am using polyethylene plastic sheet from Home Depot ---  not the best, but it's all I have at the moment. Please reply either to the list or privately to jpkleber@aol.com Thanks!
