Did Chevy EVER use galvanised frames on the C3's?
Was asked the other day, and I didnt know...a buddy said he thought Corvettes went to galvanised frames and/or birdcages in the mid-70's. Told him I hadn't ever heard of it, but would ask...
Thanks!

One of the many improvements made for the C4. Dave McLellan's book Corvette from the Inside is a great read for any backyard (or professional) engineer.

I believe this was done to promote adhesion of the adhesive to the birdcage when bonding the body panels. Perhaps this is what he was thinking of.
Given my own personal example, Forbes primer DOES NOT prevent rust. LOL

Birdcages got zinc-chromate primer for a while there. Dig around much and you're likely to find traces of it.
81 production shown; they're black here.
Bare frames were often stored outside at St. Louis and could have been rained and snowed on before being brought inside and added to the line.
