Rust under fuel filler door
A very inexpensive Z has only the following rusted area.

What I'd like to determine is whether this rust can be effectively and permanently repaired.
Has anyone here had a similar rusted area and, if so, how did you deal with it and how has that fix worked out over the long term?
To the rest, how would you deal with it if it were your vehicle (other than selling the vehicle)?
Thanks.

Screams winter driven to me. I'd guess there is underbody rust as well.
I'd assume the easiest (and likely least expensive) way to fix it would be a new quarter panel. But even then, it won't be cheap.

I haven't seen that kind of rust on a Z before, but I'd consider trying a rust converter on that area. You'd still need to properly prep the area by taking off the filler cover and masking the area around the filler neck. Then use a steel brush or other device to scrape back the area that's rusty. Once all the rust is exposed, apply the rust converter and allow it to dry in that area. After it dries and gets hard, it can be primed and painted.
It looks like it's bubbling under the seams. That would be a lot of grinding.
Replacing the panel would be the best, maybe correct, way but I don't think it would be the least expensive.
