Rainbow Dust Metallic Food Paint - Pearlescent Spring Green - 25ml Pearlescent Spring Green ready to use metallic paint, easy to apply. Use an EasyCover sponge to cover a whole cake or any other large surface, and a brush for finer detailed work. May also be applied with an airbrush (may need thinning down with rejuvenator spirit). There is no surplus pigment left on the surface after use as it is all sealed in. Brushes and sponge are easy to clean after use – simply rinse in warm water. How much is required?    An 8” round cake sitting on a 10” board, completely covered in sugarpaste, will require approx. ½ bottle paint using the sponge. Two coats are advised to achieve a smooth and radiant finish.
