In the cycling world if it rains and you use dry lube (wax-based usually) you need to re-lube the chain as the lube gets washed away quickly. For wet weather, you use an oil-based lube but it gets gunky and picks up crap. I've just used wurth wax-based lube. Does the same apply? If it rains does this stuff wash away? How often do you relube the chan if using this stuff?
