Hey! Long time artist here who paints all kinds of things, from metal lawn art to actual paintings. Rule number one- wash your bushes out in cool water, not hot or warm, as hot water can loosen the glue that holds the bristles in. Second get a small tub of brush restorer. A little goes a long way. Once the brush is dry, add a little brush restorer and reshape the tip and bristles. You can use sharp sizzors to clip and stray brush hairs that won't stay in place. And keep paining!
