I am using MM20 and like an idiot, noticed it is mixed by weight, not volume, like rebound 25 which I use often. It calls for a 10/1 weight ratio, and I do not own a scale. Question: If the silicone part A is ten pounds worth, and the pink mix is one pound, would it be logical to say that it can be mixed 10/1 by volume as well? Seems likely to me as there is exactly ten times the amount of part A to part B. Thanks!
