Once you find a clean air frame that's worthy of acquisition, fogging the inside of the air frame with Corrosion X will protect it for as long as you own it.
Thanks, Jim, the pictures are very educational! The plane currently has it's interior panels stripped out, so hopefully the pre-buy for corrosion will be easier. I've had a brief conversation with the A&P who did the annual and he mentions that there's "light" corrosion on the cabin roof... That's concerning... While a plane of this vintage may have some issues, I will ask for a thorough inspection inside the wings, fuselage, etc to know the extent of this potential issue.. Much appreciate the advice!
