I would cut out frogs stickers and spray paint frogs hoppin around. It would be awesome. On my crapy scratch's i have two frogs jumping towards each other and when i put em' on the other way their jumping away.
whati did with mine is a painted it blue and i have a decal maker and got the un symbol and put that on there and a canada flag sticker on the back, kinda funny pretty original, that's why you shouldn't do it, just telling you some possiblities, make a spike for it and put a swastica on it
dude, stencils are soo easy, but they dont work as good on a helmet (its round). normally, youd just use tagboard and a good exacto, but if you wannt stencil them, lay out some masking tape on the helmet, draw it on ther, and then cut it out. and i would suggest polyurathane or urathane clearcoat. its alot more durable than just clear spray paint. the helmet from full metal jacket would be soo dope. you kinda have to go army on it, cause anything else would look gay on a helmet designed after the army lids.
