I went with Devin's tank side protectors, and I'm very happy with them.
His pattern is exactly what I wanted, and his price seems fair, especially given that he ships immediately and overnight.
Because of my own stupidity, I got a lot of bubbles under the left side and had trouble expelling them. I finally gave up and peeled back the protector, re-soaped, re-positioned, and it's all good now.
To make life easier on the right side, I used the denatured alcohol/water solution to prep/clean the tank only, then used only the soapy water to position/apply the protector. I guess that the alcohol/water are what "activate" the stickum. But not spraying on the alcohol/water makes it much easier to position and to get rid of any bubbles. I'll let you know if mine ever begin to peel away, but so far, so good.
