Once you have a shape you are happy with and swims well, this is an easy way to preserve that shape. Wrap a piece of 1 1/2" masking tape around the plug,overlapping in the back.use an exacto knife or a single edged razor blade and carefully cut along the edge of the lip. Peel off the tape and transfer it to a piece of hard plastic that you can cut easily, I use bondo spreaders. Trace and cut out the shape in the plastic, now you can lay 2 or 3 pieces of tape over the plastic and cut out the exact shape very quickly. Usually after 4 or 5 tracings the stickiness has left the tape and I'll grab a new piece depending on how may I'm tracing.
