If you don’t have a generator, and a metal box to keep it in (a well-grounded aluminum shed would do) then go get one now.

Thanks. I have a generator in a wood shed. But I also have a metal shed, and will move it there this weekend (and will ground it). Also have a running 1966 vehicle, and extra distributors, coils, etc. in cans.

the shed needs a metal floor connected to the walls and ceilings to make a good faraday cage.

The metal could be under a plywood floor, as long as all 6 sides are connected to each other
