KR> Measuring vinyl ester resin

You certainly could find out what the weight of the catalyst is by
volume and then use that, but the amount of catalyst is not that
critical on VE (changes hardening time, not strength that I know of). 
Weighing it will also require it going into another container, going on
a scale, and more handling of it and the less you have to handle the
MEKP the better.
