Last night I crossmixed my gallon and a half of motobase. I do not have a mechanical shaker so I shook each can by hand for 2-3 mins. Then I opend and stick stirred each. I noticed that no matter how long i stirred I kept getting milky white swirls in stirring. I literally stirred each can 20 mins or so taking special care to drag the bottom grooves to get any and all settled pigments mixed but this never stopped. Is this normal? I had the same thing in both cans, even after cross mixing.
