Elvis.. you have the correct products on your list...99% alcohol is what`s in lace release and `Pure`glue melter.
Benq..have a look at page 2 of the Forum.... up near the top there`s a thread discussing UK supplies/suppliers. Hairenough posted a link to one he likes and I note they also sell Knot-sealer [ other suppliers don`t carry it] Youtube has some clips on how to use/apply it ... note the person is using a spray-on container.... I`ve never had a spray-on one..simply dabbed it on thinly with a cotton pad....MUST be applied sparingly, or it can go through the lace onto the hair shafts and dry into clumps..a BIG no-no !
