I sometimes read a blog written by a gentleman named J.E. Robison, who specializes in servicing and restoring high-line vehicles (Rolls, Bentley, and such). His recent blog entry is basically an ad for a product named Waxoyl, which he applies in his shop.
The guy seems like he knows is way around high-end cars, so I thought it was worth mentioning. His comments about rodents chewing on wires are making me think about keeping comprehensive insurance on my 1, which is stored until 3/1
