I read the post about the Doc whose plane was immersed in the floods form Katrina. This is his direct comments.
Hello Drew
I hate to tell you this but I finally got to see the airplane last week.
The little plane looked reasonably well from a distance but when I got closer I saw the water lines. What had happened was that the
water in the hanger[same one that we worked on the plane] had risen to
approximately 8-10 feet . The plane had possible floated but when the water receded the plane came to a rest with the tail and
engine in the water and the nose up.
The A&P went over the plane with me and told me that to repair it would
be a major project including rebuilding the engine and replacing all of the control surface hinges and cables . Also all of the wheels and lower metal structures would have to be replaced and he said that would just be a start.
I called the insurance adjuster and he came to see the plane and
immediately totaled the plane. He said that the cost of repair would be much greater than the policy and the insurance companies were not interested in paying for plane that had been submerged in salt water. So there the saga has ended. Sorry that I am reporting this bad news
because I know that you hated to get rid off it and had put a lot of
work into it. Hope Joellyn is doing well and the cozy project is coming along.

Yes the salt water can start a chemical reaction that will begin the corrosion process but after only a week or two, just how far can that process have gotten.
Remove the wings, canard, control tubing and cables and flush them several times with fresh water After the final rinse collect a sample of the rinse water and test it for pH. The doctor will have access to instruments that do this. Maybe even use a neutralizing agent with the rinse.
Flush the inside with fresh water as well. As for the engine, drain the oil, pull the plugs and turn it over several times. Remove the valve covers when doing this. If you can get condensation out, why not water. Maybe somebody can take the mags apart and flush them as well.
Lets think on the positive side and think about the things he can do instead of the negative side on what he can't do.
Lets not let this become a complete write off because of one A & P
When in doubt get a second opinion or 50
