Mispellings in TV Adverts

With a product name like Cillit Bang, (Silly Name!) I suppose it was to be expected but I saw an Ad today on Sky One (about 14:10 pm GMT+1) with a big bad spelling mistake. I wasn't even paying much attention but as it flashed past something must have registered so I rewound and paused it.. et voila.

The top photo was the full screen advert (as seen on a Sky+ Box) and the bottom is an expanded version of the bottom right part of the screen. "Stainless Steal!". Er chaps, you mean "Stainless Steel"?
