Best way to protect old 911 from winter driving?

[joeblow]

I am looking for educated advice on pre-winter prepping of my 71' for winter driving.

She is fresh out of restoration and does have an undercoating layer.

Please refrain from the 'park it' comments because that is not my style. I drive my cars.

I know that a good wax job is a good place to start and washing often top and bottom to remove road salts. What I am most concerned with is the under body. Are there some spray on products I should use? Washing products recommended? Any tricks used out there?

Thanks in advance!

If your drive your car on salty winter roads, it DOES will rust, sooner or later.

Cleaning above and underneath will help but you wont get out the humidity in cavities.
Waxoil or Mike Sanders will help to prevent humidity/salt/water going into these cavities.
However, these products need regular reneval and are not really meant to protect against harsh winter driving.
They do offer a good protection, though (speaking from experience).

A Permabag will help to have the car below 50% humidity, anytime, anywhere.
(above 50%, metal gets corrosive).

BTW:
Porsche was forced to offer rust protection very early in the 911's car life.
According to Piech (Biography "Autoleben"), the aircooled 911 engine "sucks" humidity while cooling down from a drive. These problem was realised because, around 1968, new car customers complained their 3 year old 911 is rusting ! From 1970, Porsche treated their cars with a underbody/wheel well coat and, in 1977, switched to a fully galvanising process. These was not out of marketing but out of neccessity...
