You will need…
A plastic toy
Spray paint (I used ironlak purchased from Bonzo)
Old newspaper and clothes, can be very messy!
Start spraying, the toy may require a couple of coats. Make sure they paint is sprayed evenly.
Make sure you are in a well ventilated area, or outside. One finished leave the toy to dry for 30minutes. You may need to spray underneath for full coverage.
