first i tested the 'paint' on a small section of foam in the back of the helmet. it had no effect. it's formulated for use on plastic model cars, so i figured there was a good chance it was safe. i did absolutely no prep beyond wiping the dust off.
the product is called Spaz Stix.
i dont' recommend doing it.
i want the only one.
i halfway expected the helmet to dissolve into a puddle of goo. when it didn't, i was pleasantly thrilled. they have a bunch of different colors and the Metallic Chrome is the best i've seen. i'm tempted to get a couple more helmets to play with.
it probably makes the helmet worthless from a safety standpoint so, please, NOBODY try this!!!!
really... i am.
