Thanks. The steel rust, but with surveyor specialize in steel, will tell me if I had a good boat or not. The biggest problem with rust is from inside. If the boat was properly maintain, then it should be ok. Will see when get oh hard.
There are 3 (what I found) steel boat in FL and very cheep (between $5000 - $8000) but all of them require welding. It could be cheaper to hire a expert and let him fix the hull. Then rip out the inside and coat the steel. Steel is the best when goes to rough weather. I am not planing to be sitting at marina after is done. Way too many places to explore.
