here's a shot of my test piece that i attacked to check how well this stuff works
on the right, you can see where i dragged a wire brush across it 20 times as hard as i could. the coatings did come off in places, but i expected it to.
on the left, i hit the bowl with a ball pein hammer 3 times.
the coatings stayed intact, even though the bowl dented.
i also tried to scratch it with a screwdriver and it took a lot of effort to even mark it.
the discolouring on the right is partly due to poor preparation and partly due to petrol staining.
that's the part i had soaking for 4 days in petrol and it only stained the silver before i put the clear over it
