Hello,
Sorry about the delay.  I was busy acid staining and  finishing a concrete floor downstairs. . . 
 
OK, back on topic, I've finished the stairwell with Synteko Solid, and it's sitting right next to the rest of the house which is done in Polyurethane. . . you can see the side-by-side sheen difference.
The application was pretty idiot proof.  I wiped my floor with a wet rag 1st to pop the grain. .. then, hit the pop-ups with light sanding.  Since the area I was doing was small, I applied the goop (it's kindof thick and really really really sticky) with a small brush in the corners, pouring directly on the wood and distributing with red buffing pad for the majority.  After 20 minutes, I went back over  and re-applied or re-distributed the finish with a red buffing pad.  After about 2 hours, the wood had finished absorbing and was bleeding oil back out, so I knew it was saturated. . . I watched a movie, came back and cleaned off surface excess/puddles with red buffing pad and paper towels.  Left it  sit for 8 hours, and took pictures.  Here's a picture in the light so you can see the sheen and compared to dusty polyurethane.
 
Here's a shot of how the medallion turned out.
 
 
Here's a shot contrasting urethane with Synteko Solid.  The blue tape separates the 2 finishes.  Stairs are Synteko Solid.  Landing is urethane.
 
 
 
I wished that I had used this for the rest of my house.  I like the natural feel of wood under-foot.  It probably would have adhered better to the oily exotic used in the rest of the house, and gives that deep tung-oil look, but it's supposed to also stand up to heavy traffic, I can spot sand and re-finish if necessary, and as long as I don't let the stuff pool up and dry, I can get a perfect finish without little bumps, dust spots, bubbles, etc.  Well, depending on my sanding job.  Very amateur friendly I'd say.
I have extra if any contractors in the area would like to have some to make a sample or  play with.
Here are some more shots for kicks.
