Release Fabric, also known as Peel Ply is a tough, finely woven nylon fabric treated with a release agent. It is used to separate the absorber breather and vacuum bag from the laminate in vacuum bagging operations.
Excess epoxy bleeds through and is peeled from the cured laminate along with the Release Fabric. Peels easily and leaves a smooth textured surface ready for bonding or finishing. Not recommended for post-cure temperatures over 120 F (49 C). Release Fabric comes 60 inches wide by 2 yards, 10 yards, or 100 yards.

About how much MAS low viscosity resin is needed to saturate one square foot of 5 oz dynel?
The smallest quantity the Mas resin comes in is a Quart and a Pint of hardener which will be more than enough to do a square foot of dynel.

Vela is using peel ply. Are the deck and cabin roof also vacuum bagged? Is peel ply a topping product that can be used without vacuum bagging?
Yes, you can use peel ply on a lay up without vacuum bagging.

Very good release cloth (peel ply)..
This fabric works great and is easy to use. It peeled away easily from my epoxy layup and did its job just as designed.
Release fabric mad it all soo easy
After installing lyayers of glass, G10 and then more glass the whole assembly was held in place by way of a hand operated jack that pressed a thin layer of plywood against the release fabric holding the whole assembly in place. Came apart after the epoxy reacted with out any difficulty.

Works great to get a smooth finish
Works great - I'd suggest you practice with a small area at first!
Buy the Other Fabric Instead!
I bought this release fabric when Jamestown was out of stock of my preferred manufacturer's product. The salesman told me it was a very similar product. It is not.I have had problems with this product in use. The nylon fabric is not nearly as thick or strong as the product I typically use. It is too thin and stretches too much, leaving bubbles and folds in the fabric. I had a lot of extra work to do on my boat as a result. Just save yourself the trouble and buy the better alternative product.
