Little rollers are perfect for spreading nice, even coats of contact cement or finish over large areas. To roll without any cleanup, dip the roller into the can instead of pouring the liquid into a paint tray. Get some on the end of the sleeve, lift straight up and carefully flip the roller over the can. The liquid will seep down and drip into the can. Then move over the workpiece for the roll-out. When you’re done, toss the sleeve and seal the can.
