paint pigment

What brand paints do you guys use and do you put anything in the bottles to keep the paint from settling? I have mostly the small bottles of m-f paint and some of bears paints. I tried to see if there was a top cap to pull off to add a couple bb's or something but it looks to be recessed and as if maybe the pigment was injected into the bottles. I also tried to microwave them for a few seconds but it did not seem to help much and I lost a bottle of silver, only had it in about 8 seconds and it busted. Any help?

there is nothing I know of to add to the bottles to keep it from settling we are blind a bigger bottles which are a lot better leashed you can shake them up we've been buying the point size I know this is more than anybody would ever use in 100 years but we do go through chartreuse pretty fast we also bought bubblegum and a few other ones that size mace the it's the most popular colors if you do you find anything out there to put in the bottles to keep it from settling please let me know there is nothing that I know of.

some people have said anything stainless steel like a nut or something, but the small bottles have no way of getting anything into. I do not use enough paint to buy the large bottles.

I was going to say I think I seen somewhere that keith said to put some small bolts in them to help.

You may be able to use some small stainless ball bearings. You use them in a spray gun while painting to keep the paint mixed.

1/4" stainless steel nuts work great. Just shake the bottle like a paint can side to side violently and it stirs it up nicely.CF

CS. That top plastic plate will pop off those small bottles. Stick a hook or something in the hole to help pop it off.

thanks everyone I will try it and see
