Start with a little acetone in a medicine cup, then add small flakes of key-top material until it gets to a nice thick consistency, but not as thick as honey. If it's to thick it may trap air and you'll see little holes when you sand. Just thin enough to flow and release any trapped air. If it gets to thick, just add a little more acetone. You'll know when it's right.
