I had it planned in advance... 3 days off, Memorial Day weekend.... The idea was to pull out my seats, give them and all of the interior vinyl and leather a new lease on life with Leatherique Rejuvenator Oil and Prestine Clean, dye the faded spots on the carpet, re-glue the cover on the rear glovebox, install my fire extinguisher(required seat removal), and get to whatever else I could, followed by installation of my new Lloyd floormats.
So, here are some before pictures. The carpet was badly faded in the hatch area, and somewhat faded on the center tunnel. The leather on the seats was very hard and dry; the rectangular pads in the center sections of the seatbacks were very hard, like cardboard. The bolsters were also very hard. The stitching seems to have pulled out between the rectangular pads in the center sections, and there is no conditioner in the world that would fix that. My goal was to get all of the interior conditioned to slow the decline as much as possible.
The next four pictures show how far apart I felt like disassembling the interior... I wanted to wrap up before the weekend was over. The front seats, console side covers, and rear glovebox are all removed. Not shown in these pics, I also removed the switch knobs from the pod.
So at this point I liberally brushed Rejuvenator Oil on the front seats, then did the same to all leather and vinyl surfaces in the car. At all times I was careful to keep the product from getting into any switchgear or nooks and crannies that it might seep from later. When I finished an area, for example the rear seats, I went back and put more oil on the front seats. Then I treated everything I could reach from the driver door, seats again, hatch area, seats, passenger side, seats again. The front seats were really dried out and sucked up the oil like crazy. Below is a pic after I set the front seats back in and prepared to leave the car closed up through the heat of the afternoon and overnight.
OK, while the car was slow-cooking, I started to fix up the rear glovebox. As you can see below, it was starting to peel up at the edges and in the center.
So, the obvious thing to do is start taking it apart. I never took the lid from the glovebox, as the hinges appeared to be pressed in pins and I didn't see any need to chance breaking something. I removed the several small screws holding the molding to the underside of the lid.
Glue of champions... My dad used to call it Gorilla Snot.
3M Super Weatherstrip Adhesive. It's really incredible stuff as long as you follow the directions. Below is the first coat on both surfaces drying.
This is the part where persistence pays off. I put fresh glue in the joint and stretched the vinyl over the lip of the cover. It kept trying to creep back, so I had to keep pulling and stretching it into position until the glue hardened. Finally it reached a point where it wasn't moving anymore so I let it sit in the sun for a couple hours then left it alone overnight.
OK, now that bright yellow glue doesn't exactly look Porsche spec, does it?
Well... I cheated.... I went over it a couple of times with a magic marker, and viola! Looks perfect! Looks even better with the molding re-attached. Done, and time to get it soaking in Rejuvenator oil. 
When I opened up the car the next day, it looked HORRIBLE! Frankly, it looked like some of those ebay 928s that appear to have been dunked in Armor-All, only worse... there was a slimy, sticky crud on everything that felt like honey, only much more gross. Actually, I had been led to expect this... the Leatherique literature explains that the Rejuvenator Oil penetrates the leather and drives all of the crud that is imbedded in the leather to the surface, whether it's sweat, body oil, salt, old leather conditioner, or whatever. Same goes for vinyl, only to a lesser extent because vinyl soaks up less garbage in the first place. That's the junk seen on the surface. BTW, I didn't go all nuts on the steering wheel because that's going to be gone soon.
The next step is to get a sprayer and lots of towels(I used paper towels and recycled them) and clean off all that gunk with the Prestine Clean product. The seats had the thickest, most disgusting gunk on them, and they cleaned right up. When I was done they felt dry to the touch, and were much softer. They didn't feel greasy or slippery at all at this point, they just felt like clean leather. It turned out that on all of the vinyl I was done after using the cleaner... it all looked gorgeous. The leather on the other hand had a tendency to sweat in direct sun and I had to drive with a towel over the seat for a couple of days. I contacted Leatherique about this and they assured me that this is because there is still more gunk in the leather and it may take another application or two of Rejuvenator Oil to completely clean and condition the leather... I will know when I'm done, as it will no longer sweat in direct sun, and the leather should no longer be stiff at all.
I purchased a quart each of both oil and cleaner; I also bought leather and carpet dye and crack filler. The Rejuvenator Oil and Prestine Clean did such a fabulous job of bringing back the black leather that I didn't bother dyeing it. I found that the carpet dye made the carpet somewhat duller-looking than the original black, so I only dyed the two areas that were the most faded... the rear cargo mat and the top of the tunnel. As you will see below, the rear mat didn't come out perfect... it is now covered by a Lloyd's mat anyway; I just wanted it to be less disgusting.
I bought a quart of each oil & cleaner and it was barely enough to go over the whole interior. I have since bought another quart of oil and a gallon of cleaner; I will use the cleaner to condition all of the leather, vinyl and rubber on the car so I expect to go through it faster. In these next few pics you can see what an incredible difference this effort made in the look of my interior. I'll post an addendum here after I treat the leather again.
Next I installed my Stable Energies mounting bracket for my Halotron extinguisher and installed the seats. Then I cracked open a beer and took some pics...
Finally I installed the fire extinguisher on the bracket and put in the new Lloyd's floormats. Isn't my 26-year-old German Mistress pretty? Doesn't she clean up nice?
BTW, I took these pix and the camera battery died before I realized that I had not yet put the pod switch covers back on. Oh, Well...
