So... this went, ok. It was pretty straight forward, but not the best results were achieved but there is there is lessons learned.
So here is the tube mounted on the rotisserie that I use
Measured and cut out a piece of fiberglass. This was a 6 ounce cloth, but it had much tighter weave that what I'd get with the Soller sock. So instead of using the sock for now, I decided to just try the fiberglass. This is different fiberglass cloth that I've used with my other projects, which is only a 4 ounce cloth and not nearly as tight of weave.
First was to wet the entire tube. I wanted to wet as I went, but I didn't really see an option. But here was the first lesson learned. The cardboard tubing is very thirsty. Make sure that the tube is fully wetted.
Started applying the cloth. Used the mark I had put on the tube as the starting point and placed the edge of the cloth along the line. Then I used dabbing of the brush to get the cloth and tube wetted together. Then brush strokes towards me to keep the cloth tightened and remove any bubbles.
I had gotten it all wetted out; and not really well as I had splotches that I'm attributing to not wetting the tube fully, and/or not pausing to make sure the tube was wetted if I found a spot. Then I applied a layer of the fabric release.
Sealed it up with the Soller shrink wrap. But that was frankly a mess as the wrap is just way too big for the 5.5" tube. Also I did not leave enough overlap on the ends; you need a couple of inches for sure. So I fixed some of the issues, and used some mylar to wrap it.
This is how it came out. For the purposes which I did it for (incl. learning) I think its fine. I'll sand it out, and then address any options.
After sanding... few blemishes to work on.
So overall, I think I can live with it for the purposes of what I was trying to achieve. Some lessons learned, which is good, so can do better next time.
