How much epoxy is dispensed from TotalBoat Traditional 5:1 Epoxy pumps?

TotalBoat Traditional 5:1 Epoxy pumps dispense 20 ml of resin for every pump, and 4ml of hardener for every pump.*

*New pumps were introduced to the TotalBoat Traditional 5:1 Epoxy product line around December 27, 2021. These pumps do not dispense the same volume as the pumps sold for Traditional 5:1 Epoxy in the past. The hardener pumps changed from having a black top to a white top with a black dot. These pumps are not compatible with older Traditional 5:1 Epoxy pumps due to differences in how much the old and new pumps dispense. Either use both old style, or both new style  pumps for the resin and hardener components.
