I do use the Supreme Slider and believe it helps, but I don't think it is a perfect tool (doesn't stick and you need to tape it down).
I've heard where some quilters have purchased a silicone spray and applied it to their quilting sewing counter/top. I was nervous what this might do to fabric, but they claim it doesn't harm fabric. I've not yet tried it, but want to do so. Definitely sounds like it has possibilities. In the meantime, my favorite (while not perfect) tool is the Supreme Slider.

I have done about 10 quilts on one piece of vinyl. i wash and air dry it after each use.
