I want to do some projects involving leaving metal bare. But, I do want to
heat it up to get some rainbow effects, as well as some other discoloration
techniques to get various effects.

Two questions ........ one, what can I use to discolor steel, both in
chemicals and heating effects, and ...... two, what type of a clearcoat
do I use to seal it against further rust or discoloration?

I'll have to repaint probably every two to three years, as there is a
sandblasting effect with local wind and sand.

Coloring and patination effects appreciated. Share your secrets.

For a clear coating, I'd use Krylon's Crystal Clear - it's an acrylic that
won't turn yellow with age/exposure.

It comes in two "flavors" - the normal thickness and one that's triple
thickness (often used for artsy/craftsy projects). For something that'd be
outdoors I'd go with the thicker version.

The stuff comes in a rattle can and is easy to apply, weatherproof, and
fingerprint proof.
