How To Make a Rainbow Unicorn - Prepping

The next stage is to prep the model, don't do this until all your sculpting is completely dry :)

Prepping is relatively easy so there is only one image...

Step 1

Sand down all the heavy seams and seals from your model to create a completely smooth surface.

Step 2

Now prime your model. I use Games Workshop Skull White Spray Paint as my primer because I like the finish it gives, use whatever you like to use or whatever you can buy reasonably cheaply. Don't buy cheap cheap primer because it creates a glossy finish that airbrushed paints and pastels don't stick to properly.

Once your model is primed he should be nice and white :D
