I was resently using testors paint today(various colors) when I dipped my paint brush into the water to wash off the paint and the it wouldn't come off so i shook around the brush and instead of the paint come off and mixing with the water it came off in blobs and swirled around(like vegi-oil in water) and when i pulled out the brush the paint stuck to it. I washed the brushes in soap and Ajax bleach but i couldn't get it to stop. i even tried new water. can any one help me? oh and just incase its relevant i was using the starters set of testors brushes.
