I am a 3 year owner of a chrome S Factor pole 50mm and I have been trying through out the years for tack because I sweat a lot, so I slide down my pole quite a bit especially between my thighs, so I get scared to do lay backs.
I recently purchased some spray from an Aerial and Pole website and its called Firm Grip. It is a really sticky spray because originally golfers and baseball players used it to keep a good grip on their clubs and bats. Well, Pole dancers and aerialists are starting to use it too. A LITTLE WILL GO A LONG WAY! You spray it on your fingers and palms and you let it dry. You will feel the tackiness almost instantly I crap you not! So please be careful because I really sprayed my hands and I literally nearly was glued to my pole. Its very strong stuff.
You will stick with this product, but I would not use it on your body because its so sticky. You might have a really painful experience if you do that.
