use some stuff called WINTAWAX, it is supposed to protect CHROME (sorry i used the C word!!) but it has an added advantage.........hee hee, it makes muck and shite STICK to your bike and gives it a lovely 'GRUNGY' look for about 6 quid. also the dogs kahunahs to make your rat look wellhard, is to "paint" it with evostick end then sprinkle on very dry sharp sand, (dry it in the microwave or a saucepan on a stove,,hell, you could even wait till summer).honest it looks horrible, just the thing to scratch the little toerags precious fingers as they attempt to 'play' with your bike!
