Any C4 rust issues?
With C4 prices so reasonable, I may consider one instead of a C3. Is there any area prone to rust?

The C4 is vastly superior to all earlier Corvettes in terms of corrosion resistance. Generally speaking, structural rust on the C4 is quite rare. As noted above, do check under the battery for evidence of acid damage. Side terminal batteries can leak acid at the terminal penetrations in the case.

The frames were dipped in an electrical galvanizing solution.

Electrically charged that is.

The top of the windshield frame is a spot. Mine had rust at both corners under the weatherstripping and some along the whole length. |

I had an 84 years ago that was a California car from day one and the windshield frame had some rust on the top,it would of rusted out if I didn’t catch it in time.

It will depend on where the car is from and spent its life. If its from the north east where salt is used on the roads and the car was driven in the weather, even rain in that area because the humidity is so high, then you might find that anything not aluminum or plastic will be rusty. Particularly the steel fasteners on the underside of the car. The aluminum suspension parts can get corroded as well from salty and high humidity conditions over the years. My first 89 was from New York and I spent allot of time getting the underside and all the fasteners cleaned up from all the rust.

I used to drive mine around year here in the nordic where we get rain and snow, roads are salted during winters etc. No rust on the frame, suspension etc. But every bolt is a bitch to open as they are rusted or oxidized solid. Basically I replace all bolts and nuts which were difficut to open and use anti seize to avoid the problem in the future. Don't drive during winter anymore though so probably there will be no more trouble like this again.
Suspension and other aluminum parts are oxidized too but that is more of a appearance problem. Also ground connections and other electric connections open to elements oxidze in these conditions. |
