Once again...MM flat black enamel drying NOT flat

Well Friends, as I said in the original thread, all common sense things aside. Of course... if there is a glop in the bottom there will be trouble. I have also emptied half a bottle at times into an empty bottle to achieve the effect as Triarius stated. All other MM flats do not do this. Only black.

I'm done with MM bottle flat black!  Its too much trouble. 

I must have gone through something like one thousand bottles of MM in my model building time. Probably have around 150 on hand right now, and only flat black has done this.

Anyway....Problem solved easy enough.....I went to the LHS yesterday and bought 4 cans of Humbrol flat black. After application.......dead flat!!!!! With no trouble!

Thanks for the responses 

 

I have run into this problem as well.  If I am going to brush paint with it, I usually pull a bit of the thick stuff off of the bottom, then add a little of the carrier at a time until it is the consistency I desire.  It almost always ends up dead flat!

Oftentimes, the flattening agent will collect in the bottom of the bottle, so that the paint at the top is semi-gloss.  Stir your paint thoroughly and while stirring, periodilay, pull out the stirring rod.  If there is a glob of paint on the bottom, keep stirring until the paint id thoroughly blended and uniform throughout the jar.

Wilbur, one minute of stirring plus shaking won't do it. Try five minutes, no shaking (shaking small bottles is inherently futile—not enough volume for cavitation effects, which is what does the trick.

It is possible that something in the formulation is incompatible with the flatting agent. Once a flatting agent (really just a flat pigment such as in the Tamiya flat) flocculates (a five dollar word for "clumps together") there's not much you can do. Adding more flatting agent usually just results in thick, goopy paint. 

Yes Humbrol is dead flat! I will now use that all the time for flat black brushed.... good idea.

The MM was indeed mixed thouroughly, though.

 

I've had this happen myself, although not recently. But if I want a good FLAT finish and plan to hand brush, I usually work with Humbrol to avoid that problem. But on the MM colors I use where am gonna hand brush I stir them quite thoroughly with a mixing blade tool.
