My 2 cents. While this is a neat trick that will work for many, and may be a temp repair to get you through until you can tear it apart....I think this is best reserved for the show vehicle that gets limited use. In the link, it was a '63 Continental and I suspect that it's not being driven much. If the seal does fail, most likely it's just a short drive home to repair. My concern is a lot of folks on here drive their trucks daily/ regularly and possibly in adverse conditions. They open and close the vent windows a lot more than the guy that only goes to shows. Be interesting how it holds up for those.
