Nah, it didnt replace the broken bit, that was just the other drum before I dipped it.
They were both in the same state.
It does fill some of the little pits though, the anodes (scrap metal bars) are now full of pits where good metal has been stripped off and deposited on the drums.
It also does a great job a freeing up siezed levers and such, I had a steel lever that was totally siezed, couldnt move it with a lump hammer. Dipped it for one hour and it was totally clean and freely moving again.
