BB's - your painting friends

You can also use zinc split shot sinkers....I have found them to be better agitator balls than bb's. Get them at Wallyworld cheap. because of the heavy metal hazard considerations today you can't get the good copper bb's any more, and have to get the copperclad steel...one scratch in the copper coat and you will end up with rust which can tint your paint. No problem with the spit shot sinkers however.

The warning applies only to nitroglycerine paint. You can shake as long as your lid is correctly set to the can or bottle.

hey good tip guys! i always see big "never shake your paint" warnings for various reasons but i still always do because, frankly, stirring is too slow and takes too long...now i'm gonna have to find me som bb's

And if you are using Humbrol or the like ( metal cans) just remeber to make a little paint mark on the can you "treated" with BB's as to not put two more, and again, ... as BB's don't flow very well through airbrushes ( I once put two BB's three times, don't laugh, it's very heavy to manage).
This method matches very well with electric paint shakers (Hobart I think) you find at Micromark.
