Yes, the product is very good. It removes all that white corrosion on cast aluminium parts.
We do not have it in Canada, so I ventured to the nearest gun shop in the US and purchased a couple of cans. May have to order a case in the future; but for real stubborn nuts and bolts I soak with PB Blaster for a few days then spray with Gibbs.
I use it on my snowblower auger differential. It makes things look real purty!
