I decided to switch Imperial Flagship's (or Renegade Runner's, they're the same) dark gray top part of the hull with the black one from Flying Time Vessel. This is how the hulls looked before the procedure. I used a butter knife and a screwdriver, and followed the steps of Mr. Dulin's tutorial. An example picture of a hull piece after splitting can be seen here. I must say that when you get the feel of it, the procedure isn't that hard, and separating the stern is MUCH easier than separating the bow!
As a result, instead of the original gray over brown Imperial Flagship's (Renegade Runner's) hull and the original black over gray Flying Time Vessel's hull, I have one black over brown hull and one which is completely dark gray.


The step-by-step gallery depicting the procedure can be seen here (when it's public). Big thanks to Mr Dulin for this tutorial! I think it's a great idea, which allows you for even more experimenting while building custom ships.
