If what are are trying to achieve is seam seal, why wouldn't you use a brush on mixture? Seam tape will seal the contact between panels but won't stop water wicking through the stitching.

Solvent based glues are very specific to the material you are fixing, so I don't think that is a good idea. A solvent bond is generally stronger since its more like welding than just gluing, but you have to get it more right. The dunlop stuff is for flooring, and I doubt that would remain flexible.
As for how the silicone works, its a mechanical bond, the glue fills in all the microscopic gaps, and itself is quite strong. i've only ever done it with normal clear selly's multi-purpose or roof and gutter, and both low-odor and regular turps, and I've sealed both sil-nylon and sil-poly tarps. Seems to work pretty well. I've had it not stick to some mystery fabric, and some polyurathane stuff, but others have had it work, so I don't know what I did wrong.
Please don't take this as an offense, you seem to be trying to re-invent the wheel. That's fine, but then you will have to do your own testing, and put your own time and money into it. If the normal methods won't work, I don't see how we would know what else to try. I feel like a downer telling you why I don't think ideas will work, but unfortunately, I don't have much else to offer.
Can you post a link to the type of fabric you are using, as well as some more of your overall design ideas? That might help us give better feedback. Right now I'm not so sure I fully understand your goal.
