How to make a Portal Gun

Step 13 Smooth and paint

The big shell wasn't smooth enough for my liking so I made up a Polyfilla mix paste (like they use for walls) and spackled the whole shell to fill in the dips and smooth the shell. Use a palette knife to spread the paste and then a wet knife to smooth things over, or just wet your hand and run it over.

Then paint both shells with the same brilliant white gloss paint used for the main body for a nice shiny white shell. You could save yourself alot of trouble if you have sheets of acrylic and a heat gun to mould the plastic into shape.

At this point i'd recommend putting Bondo on there ,bondo is amazing for this type of work. you can sand it to be incredibly smooth then all you need to do is prime and paint it.

The sweet capsule was a plastic container for mints made by a British company formally known as Trebor.  Essentially, it was just a plastic capsule that was the right size and shape.  You're looking for a short cylinder with two hemispheres at either end.  You could sculpt one yourself that is half a cylinder and a quarter of a sphere at one end to get the same shape.  But it is up for interpretation.
