Inner seal or outer seal ?
I had a problem with my drivers side inner seal along the vertical - this was probably due to years of direct exposure with window down. Some of this seal began to crack and/or become mis-shapened. The upper horizontal inner seal was fine. This seal damage resulted in significant wind noise but no leakage.
This part was very pricey for what it is, and the availability was questionable as per Roger.
What I did was partially extrude the damaged seal and painstakingly adhese it back with element resistant adhesive. Once set, I then trimmed it with Exacto blades to an even edge. I then placed a hard felt strip that I purchased at Lowes to replace the material I cut away. The strip is about 3/4 inch wide and came in a roll about 4 feet long. I carefully cut the strip to its needed length, and cut the strip in half lengthwise. I used the same adhesive and set the strip in place against the even edge that I had made previously. Once tucked in place, I raised the window to let it set using the window to apply pressure against the felt. I had to taper/angle cut the most superior portion of the strip for the defect extended where the seal turned. The next day I lowered the window and the 'new' strip was solid and immobile. I was able to raise/lower the window without any catching. It looks great and up to this point is water and wind impermeable. Cost for the 'new seal' about 10 dollars. If it were available, the seal was over 200 dollars to purchase.

call Roger - he has them. You can't jury rig that part - it is a molded peice and a bit tricky to install. It keeps out weather and road noise. You may be able to source a used one, try 928 International or 928 Specialiasts as well.
Edit - sorry - I was thinking about the upper seals. The advice still applies though - get the peice that fits, and try the big 3 as your best source. Used may be hard to find because they don't age well.

I need to do this as well. Found this video on YouTube that walks through the process.

Does it have the "Do It Yourself" manual transmission, or the superior "Fully Equipped by Porsche" Automatic Transmission?

<MORE>, please. Got Pix? They are worth a thousand words.
What exactly did you get at Lowes? Which adhesive, which felt?
I -think- you're talking about either the fore or aft "vertical" "A" or "B" post of the window frame, and not the outer, lower horizontal seal in the great video that pierpressure linked to:

The felt strip which came in a roll (sorry, but I tossed the packaging) I found in the hardware section near the door handles. It only came in white or dark brown. The color not troubling to me in that it is labeled as a hard (dense) felt and that's exactly what I was looking for. I have worked with this before in the furniture repair business. The coloring will fade over time and exposure. The adhesive was a tube of Liquid Nails for exterior use (I tossed this too when emptied). It is heat and moisture resistant.
As you can see in the PET pic the inner seal (# 19 window guide) traverses the entire window frame. About 80% of the aft vertical arm was damaged on mine. You can also see the cross sectional view of this inner seal in the circle. What I did was adhese the damaged remnants of this first and let it set. The I cut the 'U' shape of it down to a 'J' and filled this gap with the dense felt strip. I was extremely careful not to get any adhesive on the face of the felt, for the pressure of the window when closed would set it nicely in its place. If it were to stick to the glass, it might pull off when I gave the window its first up and downs. I used some small curettes to place the adhesive strategically.
My pics aren't the best, but you can get a feel for how dense and hard this felt is. The strip is rather stiff. It is perfect for a small window guide repair. It is also seated flush and and has an overall nice and inconspicuous appearance. If the inner seal were more damaged throughout, I would have replaced it. It has already been through the hot sun, and wind, while the window was open and closed. It has already been through rain. It is still unscathed. I hope this helps. So far it did for me.
