prepreg resin

Does anyone know where i can buy prepreg resin? Im looking to make some prepreg for a project we have but the outlife of normal resin isnt long enough. Is there any companies making base resins?

Why do not buy ooa prepregs?

Never used it myself, so not sure how good or easy to use it is.

From my understanding, prepreg is made out of dry fabric with epoxy that has long curing life please correct me if i am wrong.
What kind of sheet do you use to make prepreg on? can regular vacuum bag work?
