A mate had a really nice old brit bike in one, it kept the air moving and seems to do a great job. although you do have to change the filters. Not sure if just having a fan blowing on the bike to move the air wouldn't do pretty much the same thing. My bike is in an unheated garage with a liberal coating on Scottoiler FS365. I've only recently got into this product but it seem to do a great job of protecting the bike and washes off easily when required. Took the bike out for a run last week..rinsed it off and sprayed the FS365 on when the bike was still wet and the engine was steaming..still did the job..at £7.50 a litre which should last the winter and beyond its a cheaper option.
