Bought it to do one job - remove a stuck nut from a flywheel on a marine diesel that had been submerged
I had tried everything over about 2 weeks, including a 1m bar and sockets - nothing!
I also bought a 1200w generator and took it out to the boat in an inflatable
Ran the generator and used the tool for about 3 minutes
After some bubbling and fizzing and some smoke, tried the nut and it came right off!
