I think something got confused here. They have to be talking about per coat of paint on a small fighter.
Either that or our paint guy was refering too the total weight of the paint
before he put it on the aircraft. I will find out.

Good stuff. So bare metal was the better of the finishes for US Aircraft. This would not be the first time US results were different from British results in aircraft testing.

Certainly. The ocean is the harshest enviroment on earth especially for metals. Corrosion protection is probably on a different priority level in comparision to land base aircraft. Painting and scraping is a career in the Navy.

Atmospheric corrosion is primarily due to moisture and oxygen but is accentuated by contaminants such as sulphur compounds and sodium chloride (salt spray) Corrosion of steel on a sea coast is 400 to 500 times greatrer than it is in a desert. Steel specimens 80 feet from a coast corroded 12 times faster than those 800 feet away. Salt is the chief contaminant.

I imagine life on a Carrier Deck is very tough on metal airframes.
