A 1961 report on a 10 year study by University of Illinois on barn paint:

SUMMARY

Among the general conclusions drawn from this study, the following are
most significant.

1. Exposure had a definite effect on the paint systems with a red or
green top coat, but no apparent effect on the paint systems with an
aluminum top coat. ...

2. The original condition of the panel affected the amount of protection
offered by the paint system. The greater the amount of rust when the
panel was painted, the faster the paint film failed.

3. The paint systems that provided the best protection were those with a
first coat of red lead and a second coat of an aluminum paint and those
with a first coat of gray metallic zinc paint and a second coat of an
aluminum paint.

4. Wire brushing before painting gave no apparent increased protection o
the panels. If the panels had not been brushed, however, more paint
would have been necessary to secure a good coverage.

I've always considered aluminum paint to be inferior, but I guess that I
was wrong. 'Course it's still too garish for common use (YMMV).

If they can put a tint in it..Id use a hell of a lot more of it.
