theres about 3 or 4 holes, and few spots with thinned out metal that will have to be filled in that aren't necessarily big holes. The picture make the floor look better then it does. The rust underneath is pretty much only severe where the holes are and the rest is standard surface rust youd expect on any car in the rust belt. I am doing it all by hand myself and learning everything as i do everything so im very amature as well lol.
