Here is a link to the thread where we discussed it.

The mylar would never conform to a compound shape. It is rigid in-plane so you can bend radii and such, but curving in that other direction won't work.
I put down a layer of cloth, wet it, put the mylar on and squeegee over the top of the mylar. This removes huge quantities of resin out the edge, and results in the lightest possible smooth layup. I mean, glass-smooth, and as little resin as possible. The mylar acts to compact the cloth.
It is a poor man's vacuum bagging setup.
I plan on using it whenever I can.
