Andy how about finding out from Airstream how they coated their old trailers?

Perry.
Not everyone would pick a non abusive acid, simply because to them, acid is acid.
Airstream has used, in the past many years, several different types of clear coatings, that bond to bare aluminum.
They all lasted about 5 years or so, regardless of waxing or not.
Simple exposure to the sun, started the aging process.
Todays coating is not applied by Airstream.
Todays coating is even very tough against Aircraft stripper.
A relatively new panel's coating won't even be touched by Aircraft stripper.
