how bad is bad ?

I am currently working on a '69 RR for a guy that was about that bad (maybe worse). I told him to consider getting a different car. I now have over 400 hours into the car and it is "almost" ready for paint. My initial "estimate" was that it would take at least 300 hours to do what he wanted. When we got it back from media blasting, I told him it would be at least another 200 hours. Rust is a can of worms, once you open it, look out!
