In this case, I have to agree with YourMomApproves. Is not worth the hassle.
If you are dealing with a fleet of bikes a 32oz bottle of Stans retails for $25 it will do about 16 wheels and is ready to use. And if you don't like Stans, there are several other alternatives that work as well. No way I'm wasting time mixing stuff to save a buck a year.
