I can say with almost 100% certainty that your boat is PVC. The acetone wipe rubbed off some color on the red material (the same as the boat) and did not do much to the black material. That is what you would expect. The acetone, since it flashes off fast, doesn't do a very good job of softening the PVC like MEK does. This is why serious repairs should be properly prepped with MEK IMO. Here is a link to the proper steps to take to use PVC two part glues.

Don't underestimate the need to remove all of the old glue. Glue will not bond to old glue.
Another way to indentify the fabric type in this case is by looking at the seams on the tubes. I bet they are thermowelded. You can tell by the way the fabric has a hot melt edge around the areas where the seams were pressed together. If the tubes are thermowelded then the boat is PVC. The floor seams, the transom seams and the speed tube seams are all hand glued. These are the places that fail over time.
If you prep properly and observe the correct environmental parameters you can get a really strong bond. My Zodiac was in terrible shape. It had had some repairs and it was not possible to fully disassemble without damaging the fabric, so I reglued any floor seams i could work apart and reglued the majority of the transom. These repairs have lasted for years and show no sign of failing or leaking. Whether I should have just bought a new boat is debatable. But I had the time and developed the skills.
I'm sorry I missed your PM. I don't log in too often. I'll try to pull up some pics for you. Anything in particular you are interested in?
The best advice I can give is good prep and go slow when gluing. I would glue one side of the floor joint, then the other. I reglued my transom in multiple steps. I turned, flopped, strapped and actually stretched my boat so the every glue step ended with a nice easy lay down into position. No tugging, no pulling, no stress on the uncured seam at all. Be methodical.
Some will debate the real need to use MEK rather than acetone to prep for a bond. But if you try MEK and feel the result on the PVC surface compared to an acetone wipe you will see why I don't even consider using anything else. Remember, you are going to be in a hot climate. Don't mess around. You want the best bond possible.
