Raka says that there pumps pump one ounce of harder in each pump. Just to make sure i tryed the pump in a cup of water. I pump it two times in a mixing pot with graduated measuring marks witch should make it 2 ounces. Well it didn't it fell just short of the 2 ounce mark. So what do i do add more till it makes it to the two ounce mark or leave it as is? i'm new to all this epoxy pump stuff. marc
