gwinger, had the exact process down pat, how I have used Eternabond
Tape in the past on both my front and rear cap seals, around vent pipes, antenna cable opening, and the satellite dish cable opening. Clean the area with some kind of alcohol solvent (not petroleum based), and put down the Eternabond tape first. If you have a wallpaper roller they work great to smooth down the tape paying particular attention to the edges for a good seal. Afterward, seal around the edges of the tape with Dicor for a little added protection. After that, no need to worry about the seal or leak from the repaired location.
