This is the brand I have used.
Amazon.com: Incom Manufacturing RE3848 3" X 15' Awning Repair Tape: Automotive
You can find it in many different RV type stores or online. Shop for the price.
I have had it last several years in patches that roll up in the awning. And it bailed me out this June before our 1,600 mile RV trip this summer as my awning up top is in real rough shape. I had to tape the entire length.
However I did use some of it up top last year on the awning and this spring it sort of dissolved. Do not really know what or how. I have never seen it do that before but it was toast after 1 season on the direct up top area. It is like maybe a cleaner I used affected it.
The duct tape, this is even more temporary. If you are looking for 6 months, the duct tape "might" hold providing it is high grade tape. Gorilla tape will be better however the colors may not be to ones liking. I used regular duct tape over my compartment locks so water does not freeze in them when we winter camp. I fold it back over itself to not have a sticky tab on both side and leave a 1" exposed sticky you stick to the door. This creates a flap over the lock. Many years ago you use to see these rubber flaps over padlocks out doors. It did not last well but made it through a winter no problem.
The sun beats the regular duct tape up pretty bad. However the Gorilla tape is now 2 years and counting, winter and summer and as good as the day I put it on.
The awning tape is clear and looks really good over the awning.
Later this year I have to replace the fabric on the main awning. It will not make it another year.
Hope this helps
