Surface Corrosion?
I'm working on a little aluminum airplane that has some surface
corrosion just under the paint in a couple places. What do you guys use as a treatment to stop the aluminum corrosion? I remember 30 years ago using phsophoric acid then a zinc chromate converstion treatment. Is this still the best technique to stop the corrosion? I need to just abate the current corrosion from expanding. What do you guys recommend? BWB

Etch and alodine is still the best way.
Use a 3-M 7447 Scotch Brite pad to help remove the corrosion. A good epoxy primer followed by topcoat and you should have the problem solved.
