Each bucket with 15 kg. mixed resin. Room temperature is 28° C. Don't try this without a special formulated mixture for vacuum infusion. This amount of mixture will explode with a normal hardener. Much of this will come out, leaving a typical resin to fibre ratio of approx. 1:2. Note the pvc tube as first resin trap (and a little deformed by heat build up in the bottom at the end of the previous infusion session)
