I did my rear tire on my Tenere 700 last month using the method recommended by Woody's Wheelworks. I ordered an Outex kit and lower profile stainless nipples from Woody's.
The first thing I did was to change out the factory nipples for the stainless ones. Make sure you use a little anti-seize to keep the nipples from galling against the spokes. After the rim was trued up, I wiped down the rim with acetone to remove any oil or grease.
I then sealed each spoke individually using Goop Automotive glue (per Woody's advice). After the glue dried, I went around cleaned up and removed any glue strings. I also trimmed the glue with a razor knife to make sure the tape had room to seal between the glue and the shelf where the bead sits.
TIP: The glue will settle and run, make sure the glue is set before turning the rim to the next group of spokes.
The next step was the Outex tape. I heated the rim with a heat gun until it was warm and started applying the tape per Outex's instructions and made sure not to overlap the tape at the end. I used an aluminum tire spoon to make sure the tape was pushed down properly to seal against the rim starting in the middle and working toward the edge attempting to push out all bubbles. I also used the heat gun to heat the tape a little as I went along.
After getting the tape sealed the next step is to place the protective layer on the double sided tape you just applied. I applied the protective layer the same way I applied the tape, using the heat gun and tire spoon.
The last step is to seal the gap between the start and finish of the tape. I did this by cutting a small portion of tape and centering it over the the gap and then cut a piece of the protective covering and placed it over the tape. I decided to go an additional step and sesl the edges of that covering with the goop to eliminate a place for air intrusion.
Now all you have to do is put in your valve stem and let the rim sit a few days for the tape to properly settle. DONE!!!
P.S. I lose less air since sealing my rim than I did with the tube in.
