Getting it done is no big deal. I have it done to my airplane every other

My airplane has been parked two miles from Mobile Bay for six years and
shows no signs of airframe corrosion.


Good news for a change! For some reason I had it in my mind that the
process was fairly involved and thus expensive. Our Arrow has nearly always
been hangared, and corrosion has not, to date, been an issue. But now our
mech is seeing some very minor powdering and recommends the treatment.
We'll probably get it done in the next couple of weeks.

I previously co-owned a C-172 that spent its entire life (18 years when we
sold it) outdoors, never had any anti-corrosion treatment and never had any
serious corrosion issues. This is in Seattle, so the plane got rained on
regularly. Apparently salt is a much bigger issue than wet. The plane was
parked at BFI, less than a mile from Puget Sound (sal****er). But there is
very little salt in the air and on the ground here. Humidity in summer is
generally low, and no need for salt or other chemicals for clearing ice from
roads in winter.
