x6 but really, depends on how you want to do it. I've just used fiberglass resin without the cloth sheets for some things, but the sheets make it stronger. What are you planning to do? that would help greatly. Wear gloves, have the resin, sheets of fibers, activator, and some kind of heat source whether it be the sun or heat lamp. Then you will also need a heavy grade sandpaper like 40 or 80. I use tons of activator in mine so I'd get extra bottles. Also will need a brush and tape. You will tape the brissles and cut them near the base. YOu will use this to pop the air bubbles out of the fibers. It's pretty easy once you figure out how to pour it smooth. Hope this helps.
