Like Betty&Sully already said, popsicle sticks work great for doing it and they are cheap so you can't go wrong there.

What I use is the handles from my disposable brushes that I use for finish. After I use a brush for finish I just snap off the plastic handle and put it in a drawer and then use them for getting the epoxy out of the jars.

You'll like the Ultimate gel, that's all I have been using for the past 2-3 yrs now myself. Great stuff...although Part B really smells like a dirty foot thoughlol
