I'm late to the party but if they are really concerned about corrosion in
the rebar maybe they should look into getting some of the (fairly) new stuff
called MMFX rebar. It is five times as corrosion-resistant and up to three
times as strong as conventional steel. He could use less steel and it would
last longer than just about any other comparable product. Ameristeel is
advertising a product called "Z-Bar" that is better (per their claim, not
mine) than just plain epoxy coated bars, but I have not been involved with
any project that used this material, so I can't say anything one way or the
other about it.

Yep. It's an epoxy coating. It's used in construction where the
rebar will be subjected to harsh conditions and rusting is an issue.

The main culprits in attacking the rebar, salt and water, don't have
nearly as much effect on concrete. Protecting the concrete would
require protecting large areas, and periodic reapplication of whatever
it was you were using to protect it. The epoxy coated rebar has a
much smaller area (in general) and it's a one shot deal.
Your bones are encased in meat, but you can still break your bones
even through the meat. That's why Wolverine has an admantium skeleton
- I'm amazed I have to tell you this!!!! ;)

My son has been a Logan fan since day 1 and has 100 copies of
Wolverine#1 in Wizard archival bags with boards.
(I only have 1 copy)
Just yesterday he emailed me a picture of a razor he purchased -
Wolverine version, Gillette brand, for keeping nice crisp corners on
those 50's style sideburns Logan sports that the ladies find so
appealing.
