I'm more convinced than ever that createx simply has some consistency issues. With each bottle of paint and each bottle of additive I've used viscosity has been all over the place. I've had Some very thick white and some white that was thin enough to use in a .2 straight from the bottle. Additives seem especially prone but not reducers. I agree with @SiRoxx 0n the probably 4030 The paint, 4004 and especially 4030 all seem to have consistency issues. So heres the sciencey part.....LOL I doubt a bad batch of reducer, heres why; 4012 and 4020 from the docs are identical except that 4020 has somewhere between 5-10% acetone added if i remember right. The 2 buotxyethanol ,aka monobutylether, aka glycol ether ,aka a whole bunch of other names is the other non- water ingredient for both. Acetone evaporates quickly then water then the butoxy evaporates slowest. So left open 4020 becomes 4012 pretty quick and then concentrated 4012 pretty slow. Somewhere along the line, either in shipping or at the plant some of the stuff is allowed to partly crosslink . I'm not really sure if its at the plant and when they bottle it the bad bottles are literally the bottom of the barrel or if its just storage and shipping after the fact. If youve ever tried to put down a new coat of enamel paint over enamel thats past an hour but before 24 and seen it wrinkle, the seeding is that same process but in suspension.
