over the weekend I spent some time on the tank. I had to drill the tank lid to get it off. key would not budge even after soaking it multiple times with penetrants. I also got the sander out and scraped off the paint. after using the dremel to open up some of the rust holes, I ended up cutting away sections. I think there's still more to cut away, but I want to talk to someone about repairing it before I got further. some of these are very small holes and could perhaps just be spot welded closed. someone suggested a radiator shop might be able to do the work.
