Welcome! And id be interested to hear more about chassis protection if anyone has any insight too

In nearly 30 years I've never applied any chassis protection apart from localised touch up. I've only repainted the front and rear wishbones a number of times.

I am affraid that outside visible rust is nothing compared to what is going on Inside chassis (and wishbone etc ) profiles. When i have any rivets off etc access to Inside profiles always spray there Inside some protestant tectyl etc with long tube and mist . And NO contact with salt on roads .

Outside is easy to see and clean and paint . Inside is issue. 

Below is wishbone bracket snap off. Outside was fine powercoat no rust. But when repairing - this thin 1 or 1.5 silly profile it was welded to..  rust.

Especially if you use the car over winter, it's a good practice to treat the chassis with ACF50 or similar to slow down external corrosion.

Also, as @Andrzej said, internal corrosion is an issue as well. Humidity trapped inside the chassis tubes can condensate with the cold, and start corroding the chassis from the inside. To stop this, there are specific products, like Dinitrol ML, which fully cover the inside cavities with a waxy film, preventing corrosion. You can get inside the tubes using the rivet holes if needed.
