This versatile scale is the most accurate way to measure resin, regardless of the mix ratio. Also, weigh your dry fabric and only mix enough resin to achieve the desired 40-50% hand lay-up ratio. This scale will measure up to 5lbs or 2000g with accuracy to 0.1 oz/2g. Measure the resin, re-zero (tare) the scale, and pour in the proper amount of hardener. Mixing couldn't be easier.
