Hey Aaron...

Enamels do serve a purpose still but it wouldn't be a bad idea to start the shift at some point.  There are a number of "sets" that you can get that won't set you back and gives you a good starting point. 

Spud has it right, with a couple drops of water the Chipping fluid thins a bit and sprays nicely.  I have just turned up the pressure a bit and spay one to two thin coats.  You don't need to soak the job to get the effects you need.  Simply dampen the work surface in the area you will be working on to chip after you paint and then use a number of tools to aid in the removal of the paint to get the desired chipping effect....Fine paint brushes, stiff bristle stippling brushes, damp cotton swabs or a dampened, soft toothpick to lightly remove the paint from the areas.   You will have fun with this stuff!!!
