Installed my case awning a couple three months ago. Used the "putty" tape stuck to the back of the C track then Dicor at all the edges, I'm leak paranoid. Be REAL sure track is hitting solid material in the wall and no wiring. One big caveat that shouldn't be ignored is making sure the C part of the track is evenly open and DO spray the inside of that puppy real good with silicone lubricant. Should be no brainer to have another pair or two of hands there as it's not a one person slide in project. Secure each end of track with a metal screw to prevent awning sliding either way. Not real complicated just needs thought out in advance and don't skip steps.
