This is very cool stuff, I also used the test stuff (just found out what is was last night). For about 3 weeks now the stuff lasts and very slippery. I used that Silk stuff before. No comparison. SlipStic is much more slippery and works great when it gets hot and humid in the pool room. I'd like to find something for the wrap on my cue's butt that works the same. I noticed that because of the humidity my wrap was damp and the shaft was super slick. I sent them an email to see if this would be OK on the warp. Many thumbs up from me, best product I used yet.
