Hi again leamon .. I left a further comment on it on another thread just to the effect that it held great overnight etc. but [as I was expecting] I did a heavy bit of exercise next day here at home as I have a room kitted out with gym-equipment/machines and after about 20 minutes once I was sweating heavily, the bond then loosened to the point where I could easily remove it..no problem there though as I wasn`t in a public gym with other people around...so I just took the system off, and carried on with the exercise... I didn`t wipe off the remaining Got2B from the scalp... I then cooled down normally while having a shave, and noticed that just before jumping into the shower, it had gone very tacky again on the scalp..... I assume from that, that in the event a wearer was maybe sweating a bit more than normal during a day [let`s say at work or wherever ] even if the bond lost some of the grip, it would re-hold as soon as the person cooled down normally again. potomoc was saying there that it washes off easily---yes it comes off very easily if you take the system into the shower with you and rinse it under the flowing water, I didn`t use any shampoo or anything ..just a good rinse and it came off the lace and the poly very nicely....no mess/residue . I`d advise anyone intending going to a gym to use `normal`glue/tapes though......but sure the Got2B is really easy to work with and I`d suggest newbies have a tube to hand to help them get used to bonding ---if you incorrectly position the system, it`s easy to adjust/lift it etc without hairs becoming stuck to glue and all the hassle that can give `learners`......by the way guys, if that actually does happen you, or hairs get stuck to parts of the tape, just dab a little lace-release onto it on the tip of a finger..this will release the trapped hair avoiding them getting broken/snapped off. A good `tool`to have handy too, especially for full-cap wearers, is a bottle of `Re -align`` which you can spray on to keep the glues temporarily non-stick while you position your system.... it`s good to have it to hand as a newbie..it can be very helpful....cheers guys.. Paul.
