Rust on Exhaust Flanges

[Kelvin]

I have a brand new Z. I just happen to look underneath my car and noticed rust on my exhaust flanges. Is this normal? Or should I take it back to dealer and have it treated. Also some surface rust that seems normal on other areas; but it’s not too bad. Car has 120 miles on it. Bought it brand new from dealer.

I also have rust. It's normal unless the rust is very deep to the point where pieces of the metal are falling off. The dealer won't do anything about rust (for free at least). You can buy some rust prevention spray and apply it to areas that show some rust. You may have to sand and clean those surfaces before applying the spray.

Thanks!!! Really appreciate the info. That’s what I will do. Again, really appreciate the info.

You can buy "rust converter" as a paintable liquid or in spray cans that converts the rust and makes it inert (nonreactive) and it actually protects the original rusty spots against future rust. The rusty spots will turn black. I believe some converters don't need to be washed off before applying preventer, just need to be dry. I'm not familiar with the prep needed before applying a preventer (like degreasing, etc...).

Edit: I did just read that you should NOT use "converter" on clean (not rusty) metal as a preventer.

Thanks. I just used some rustoleum high heat rust stop spray. Also, dealer said
they will look at it during my first oil change.
