Experience is a great teacher. After owning various Corvettes over 40+ years, I realize that rust on our C6s is the last thing to be concerned about.
Today's materials including alloys, sealants, and manufacturing methods as well as every other aspect of these cars makes them immune to most rust conditions. Some of the alloys may develop protective oxidation coatings and make them appear less than perfectly new, but these parts will not rust, weaken, and loose structural integrity. Suspension parts are especially beautiful when new, but develop a dull, irregular coating over time.
It is wise and often enlightening and useful to consider potential problems and remedies before they cause damage to hidden or exposed parts. I have put the rust and decay problems prevalent in several of my previous Corvettes into my archived memory and moved those memories off-site!...:L

A Frustrating Rust Story:
My 1975 coupe -- which I bought new and garaged everyday -- developed rust which bloated, rotted, and weakened the surrounding steel. This condition developed on both doors where the window regulator was bolted to the door end frame. The rust was easily visible when looking at the door while open.
I believe it was caused by galvanic action -- a normal event between two different metals when held in close contact.
Everyone who noticed the damage, which grew to about a two-inch diameter after two decades, announced that they "knew" the car had been in an accident... which I knew was not the case. When I mentioned galvanic action, they became defensive and "knew" with even more certainty that their accident theory was valid.
I believe the device mentioned on this thread might have stopped or slowed that destruction.
