Thanks for the speed checks all.

To use projection mode, you mode the model so that the area you want to paint is face on to you then press F8.
Although the screen will flicker slightly, the image should be the same except you can paint outside the model now.
Imagine a sheet of glass in front of the model. You paint onto the glass, then when you hit F8 again, it projects the image onto the model texture(s).
The advantage of this is that it will look as you painted it no matter how twisted your surface is, It also respects UV boundaries and stays inside the texture edges.
