However, the picture of the container says 27.5 ounces. Which is it?** A: The WEST Systems products are sold in several sizes. 7 oz round cans, 32 oz rectangular cans as shown here, and large rectangular cans of 126 oz. Try to confirm the size you are buying. **Q: Shelf life of 205 hardener? My cured epoxy (105+205) is soft, gooey, even when measured exactly with a syringe.** A: I believe 105 resin takes a higher proportion of hardener than 205 resin. Check the directions. **Q: How much faster than the "slow" hardener does the "fast" one cure?** A: On the manufacturer's website states cure time is 6 to 8 hours. The pot life at 72 degrees Celsius has 6 to 12 minutes to work with. **Q: Will the pumps work on the smaller 7 fl oz cans ?** A: I believe that if you purchase the set of 3 pumps, the smallest will fit the smallest container which is, I think, a pint. If you don't routinely use something like an eighth cup or more, you might want to consider buying some syringes from a farm supply store (a 60ml syringe for the resin and a 12 ml for the hardener). I recommend these sixes because the epoxy is mixed at a 5:1 ratio of resin to hardener and syringes of these sizes mix one major increment of one to one major increment of the other.
