The cloth is .56 or .7 oz per square foot cloth; it is thin and almost paper like you can use either finishing resin(tougher) or water based poly-urathane(lightest). You lay the cloth on the surface and drizzel a little resin or poly on in the center, and spread it out with something like an old credit card. You want just enough to wet the cloth and lay flat without bubles; the rest is scraped off. Do one side at a time and let dry. I just got a hold of a NIB red box Corsair about 3 months ago by luck.
