Yeah, and some builders swear that house enamel is the best aluminum
paint on the market at any price.

And most builders are in, done and gone and if it's cheap it's great.
They never see it flake and peel a year or two later. The reality is
that if it isn't made for the job it won't do the job and no amount of
hearsay will change that.

That was in reference to experimental *airplane* builders, Joe, not spec
house hustlers. There are a lot of very expensive paints for aluminum
airplanes, yet there remains some doubt about whether they're even
remotely worth the premium price. If it's good enough for an airplane,
it's good enough for a screen door. Of course, we all know how
significant a role preparation plays.
