zestybeard… No I kind of meant make your own, it wouldnt be difficult if its not got loads of shape to it (its just the shape makes it awkward to stick the graphic on), round tube or flat bits are a doddle, make your own stencil with card then mark it on the back of the vinyl or fablon (think back to front for that bit) and cut it out, you can buy the vinyl readily enough from a sign shop…. Or just fablon from B&Q or the like (not bought any for years), it would at the very least give you an idea if your scheme is a good one, at the worst you lose just a few quid trying.
Of course if you cant hold a pencil, pair of scissors and a craft knife, then your ferked. 🙂
Do it right and it will be fine, do it wrong it will look poo, but you have still only lost a couple of quid, if you cant make the stickers, you have zero hope of painting it yourself.
