I sprayed
this shell using only rattle cans (linky cos it's HUGE, sorry).
The orange swish, lettering and the bonnet logo were printed onto the back of waxed paper (the backing stuff for that clear book covering you get from 'smiths is perfect), masking tape applied to the waxy side, then cut out using just scissors. The black/silver fade was sprayed first, then the masks removed and the detail filled in layer by layer after. I still have most of the can of light blue left over from tinting the corners of the sunglasses...
I've since gone crazy on an airbrush setup and paints from Jon, so I will probably never go back to my large collection of rattle cans!
