After your epoxy is thoroughly dry it should look something like this.  The epoxy that you choose is very important.  You don't want something that will set up too quickly and cause you to rush when working out the air bubbles and wrinkles.  On the other hand you don't want to wait for days in between steps.  The epoxy that I bought actually set up a little too fast for the size project that I am working on.  I had about 30 minutes from the time that I mixed it until it was to sticky to work with.  Fortunately I was able to get everything finished  before it set up.  I always let my fiberglass cure for 8 or 9 hours before moving to the next step.  You don't want it to be even the slightest bit tacky.
