I used it to remove a very stubborn locknut from a bicycle headset. I had tried just about every recommended technique but to no avail. This was the last resort and fortunately it worked. It's not cheap but will probably last a very long time. Very impressed.
Good reputable maker .
Used this for a number of years .My work in caravan service,, we saw lots of rusty nuts. Rust was a common thing on the chassis and running gear .. .But after showing the nut this rost off ice they soon gave up .If you have a nut that thinks its the boss get a tin of this and show it your the boss .
Effective and extremely useful to have in the garage.
Needed to remove 3 very seized steel bolts from an Aluminium cylinder head thermostat housing. The bolts had not been touched in well over 22 years and refused to budge. After 2-3 applications of this product all bolts were removed without any damage to either the bolts or, most importantly, the cylinder head threads. Can't speak highly enough of this product - brilliant stuff.
