Good for pub talk. Like sticking a turbo on an otherwise standard clio. 'My car is 300bhp m8'You also can't touch or get within one meter of the wreck unless you own it.
but I don't think you can stop other people from diving around it, as long as they don't touch.
So essentially you're buying f**k-all.
You can't use modern steel in things that require exceptionally low radioactivity (https://en.wikipedia.org/wiki/Low-background_steel). Since nuclear weapons testing started in the 40s, all modern steel carries a small but significant amount of radioactive material that makes it less than ideal for that kind of application.Wtf would you do with it.
