I've used the vinyl backing on a few client tanks and my home tank, it looks great and works great you just have to take your time putting it on so you don't have bubbles. A tiny bit of dawn dishwashing liquid mixed w/ water, spray the back of aquarium until very wet and also saturate the actual vinyl sticky as you peel the backing away, lay the vinyl on the tank and use a squeege or credit card to work out the bubbles starting from the middle out. The water/dawn mix gives you longer work time on the vinyl in case you put it in the wrong place and keeps it from sticking together too. any small bubbles left use a hair dryer to heat them and work them out or take a needle or razor blade to pop them and work the air/water out. trim out the excess and your done. You can buy the vinyl from most any sign company.
