I use Lee Liquid Alox. Put a handfull of bullets in a pint plastic bag. Squirt in a half ounce of liquid Alox and shift everything around until the bullets are coated. Pick the bullets out one at a time and stand them on their base on some aluminum foil until they dry (sometimes takes a day or two). Save the bag with the remaining Alox. After the bullets are dry repeat the process to give them a second coat.
