corrosion evaluation report on the F-22 and F-35, completed at the end
of September, says:

"Corrosion of the aluminum skin panels on the F-22 was first observed
in spring 2005, less than 6 months after the Air Force first
introduced the aircraft to a severe environment. By October 2007, a
total of 534 instances of corrosion were documented, and corrosion in
the substructure was becoming prevalent. For corrosion damage
identified to date, the government is paying $228 million to make F-22
corrosion-related repairs and retrofits through 2016."


That's the trouble with metal. It corrodes.

Maybe the manufacturer should speak to the european automotive
manufacturers who by and large have managed to make cars that resist
corrosion provided they are maintained properly.

It would have been far better to make the aircraft out of composite
materials, otherwise known as "plastic".

Cameras made out of metal, planes made out of plastic and dresses made
out of meat, my god it's madness, madness I tell you!!!

I think my cat may be part methane.

Apparently you are not familiar with the Alfa Sud (life expectancy
18-36 months) and various 1970's & 1980's Lancias.

Alfa Suds where the worst by far and IIRC had to recall them here in the
UK as most where failing their first MOT (roadworthiness test done on
cars from the third anniversary of registration). Since then they have
improved enormously.

Try the japanese. I haven't had a corrosion problem in a Honda within
the last 25 years. My current car (Legend - Acura RL) is 13 years
old with no noticeable evidence of corrosion. Mind you, we don't use
salt on our roads.
