Debbie sells knot sealer ...click the `accessories` link. You also need lace- release....it`s cheap and it`s as well to get 2 bottles as it`ll be one of your most frequently used products along with `Pure` glue melter. You appear not to have any glue on that list...I`d advise you to have at least 2 types [small sizes on your first order] as an alternative to or indeed to be used in conjunction with tape... most guys [ or at least many] who use tapes at the back and sides prefer glue for the front as it`s the most visible and you can get right out to the very edge with glue ....tapes can be tricky at the front due to the shape of the front hairline which is not straight .... applying glue can be a lot easier....again, you have to `experiment` with various glues/tapes to find what suits you best.....regards, Paul.
