I will be coating all bike left outside in the rain with a layer of Boeshield T-9, then a layer of LPS-3, then some ACF-50.
My plan is to be able to leave my cruddy bikes like the Huffys and beach cruisers outside in the rain and if friends want to come ride, they can just jump on a bike and ride it, no tune-up needed! My main problem with these bikes in the past has been: The chains and cables and shifters and brakes and steerer tubes and bottom brackets and wheels all rust up over the winter and then people come over to ride on a nice day---and the only thing not broken is the tires, still inflated :/
