You'll have the decanted paint ready in a couple hours or so simply (very careful!!!) introducing a toothpick in it, than a couple than 3: the toothpick tends to accelerate the gas release : but you must have room in the jar to leave the gas boiling: just careful introduce in the right decanted paint the first one, when you'll be sure that it would overflow leave it fall in the jar, than the second and the 3rd: leave them for a whyle: after 1-2 hours you'll shake the product and reduce it with no hazards
I done it yesterday withe the TS14 fr my GZox: I must say thet the black needs a lot more thinner than other colors I decanted.
EDIT: obviously I meant wooden toothpick
