high altitude balloons are a good idea but i fear when they go pop and people find this shiny strange material dotted about it'd turn my sleepy village into roswell mk11.
paint rollers...i like your thinking but they wouldn't fit (749).
i saw the caps from Ducati Kanma in a post on here which gave me the idea to have a crack at making something similar (but not as good looking).
i dont want to buy them because i just want to keep it quiet whilst it's warming up and thats it.
