It'll be the same bike as my summer ride as I only got the one

(Abigail doesn't count on account she lacks a fitted engine, carb, loom, any sort of lectrics, brakes, tank, seat, blah, blah, blah!)
Think the difference for winter will be when I decide to stop cleaning her. Used to try and wash off the road grit on weekends and never managed to get to it before it got to the bike. This year (and soon) I plan on giving the old girl a final really good scrub then coat her in grease/spray oil and let winter do her worst. She can live out the winter under her protective layer then get a really good scrub in the spring.
Any reccomendations of a suitable protective gundge to smear over her??
