I just did a Google search on it again and came up with this http://www.hairdirect.com/store/Aquabond...e-1Oz.aspx
I note the application instructions state `Apply a thin coat to the scalp only ..allow to dry until tacky and attach system`.....that`s the first time I ve seen instructions advising one coat is sufficient.....it also says a bond/hold time of 2 weeks is possible, depending on the usual things/factors. I`d advise any wearer not to go for really prolonged bonds, for several reasons, not least of which is health.. even if you only do a perimeter bond [as opposed to all-over or partially across the center of the scalp] the skin under the tape/glue is trying to exude sweat/oils etc. and is also shedding tiny bits of skin......bacteria and sweat build-up will eventually cause irritation/itching etc. at the very least...in my humble opinion you should aim to develop a regular de/re-attach and scalp-cleaning care routine, to avoid such issues. Waiting until the glues etc. begin to fail will give you more of a mess to clean up too---some of the products can literally be good/strong one day, and overnight , turn into a gooey mess leaving you with a big clean-up job requiring loads of time and effort..... keep your wearing as simple as possible....that`s just my 2-cents worth anyway...
