I have tried Sally Hansen Airbrush Legs in 3 different shades. I think it does offer good coverage but I can't seem to find a perfect match for my legs. Also, as it is quite humid here, the 'foundation' does tend to smudge on chairs when I sit down.
I can get Air Stocking here but I haven tried it. Its more expensive than the Sally Hansen one but the shade selcetion is not that great(only 3 shades). I was surprised to see that its from the US coz when they had juz arrived to S'pore, I think magazines had marketed it as a Japanese product.
