The first task was to clean the windows after the bus was previously used as part of Jo Peel's Pipe Dreams animation.
Next step was a couple of coats of white paint.
Then the fun began with some acrylic paint bombs...
and continued with the super-soaker.
Next up we pierced a few spray-cans to get some big splashes of colour.
Then the task of tying it all in and blending the colours together.
The final piece.
Job done. It probably won't win any beauty contests - but it was bloody good fun!
