Default C4 frame/ underbody question

While working under my car, I have noticed some light corrosion along the frame rails. Was the frame a bare aluminum, or was it painted/protected from the factory? I tried looking for pictures but had no luck. I am thinking of removing the corrosion and spraying some black or gray epoxy.

The C4 has a steel frame. It wasn't until the C6Z06 that Corvettes had an aluminum frame.

Ok, thanks. I have some black epoxy that's begging to be used.

The uniframe was built of high strength steel that was zinc- coated or galvanized before it was primed and then painted black.

It ( The C4) was one of the most rust-resistant cars of the twentieth century.

I didn't know that , I guess GM learned there lesson on the C3.. Alot of C3 Corvettes have rusted frames so bad they can't be repaired. I have seen C3 frames that were rusted completely through......WW
