I have in the past calculated the mix weight on epoxy based on the net weight of the 2 bottles. The specific gravities are quite different. But West comes in different size bottles (not 1:1 mix).
And since I was too lazy to walk to my shop and read the instructions I figured there were enough knowledgeable individuals on this exchange that could rattle off the numbers. :-) (Just in case it was not in the directions.)
