Why would you risk leaving the house at all on delivery day?

The simple fact of the matter is this -
 
There is a sliding scale for protection in each category that moves between PROTECTION and ease of APPLICATION. Its not a hard and fast rule, but generally the easier a product becomes to apply its generally at the expense of longevity.
 
I've got plenty of prototypes in my office that are just stupid-difficult to apply, but they are practically impenetrable by traditional sealant standards. In the end what good is a product that makes application long and difficult? But at the same time if its super easy and doesn't last long is it any better?
 
Key is to find balance... a small investment of effort/time will usually translate to better durability. Things at this point are just at the physical limits of modern chemistry. They gradually improve, but something that is sprayed on and then left will generally fall short on durability compared to a similar compound that requires a more traditional application.

195 HP Corvettes thanks to fuel economy concerns and engineers still grappling with emission controls without the benefit of EFI and computer controls.

It's hard to believe how bleak the automotive scene was at one time.
If you would have told me in 1979 that Chevy would be making 600 HP Vettes and 500+ HP Camaros in 2014, I would have thought you needed to be commited.
