Hi lee99 , Yes I attached it straight away but only used a thin coating as it was just a one -off try out to see what way it would be like....it`s been a while since I used Got2bglued .... was happy enough with it.... I removed it last night and some areas had that white residue .. I did what you described....rolled the lace under running water.... I`ve used it before when going for a cut-in.....it`s fast and convenient ....just got to be careful that the stylist doesn`t keep spraying too much water onto the hair ! I`ll use it again this weekend as I`m off for a few days....certainly the advantage is no fiddling about with tapes...just smear it on and pop the system onto it !
