After about two hours of cleaning up the Titan with my dremel and a hand hacksaw, I spent another hour scrubbing it down. I used a dremel (with an extendable shaft) and a cutting head to trim off the excess flash from the pour points. This took a while, as it is a bit of a pain to set up all the items you need to do it right. I followed a guide by Ichiban, a fantastic painter and modeler out of Japan. His YouTube channel is way worth subscribing too.
I can't say enough about this guide, it is well worth taking a look at if you are assembling a Titan, or other large resin model.
After I was all done I was left with this.
