To be continued...
First as many rivets as possible should go into the main bows.
Using 4 inches between the rivets plays it pretty safe, especially on the curb side.
Scatter the holes out and then mount the rail with either Cleco's or #8 screws.
Then drill all the holes you wish.
Completely remove the rail, and remove all the shavings.
Apply a bead of Vulkem sealer on the backside of the rail, making sure that bead covers every hole, and is continuous from one end to the other.
Install the rail with the rivets. Some sealer may sqeeze out of the bottom of the rail, so clean it up asap.
Lastly, install a bead of Vulkem on the top side of the rail joining it to the shell.
If you use Vulkem, it does not set up very quickly, so that buys you time.
If you use Sikoflex, it does cure out in about 1 hour, so you must quickly clean up any boo boo's.
You might check out the curbside awning rail and make sure it has plenty of rivets, and that it's properly sealed.
