Hey Goodluck...I think you are referring to Fray Check...you can get it at walmart in the sewing section real cheap...just use a little on your finger and spread on the very edge of your lace...the only problem with this is after a day or two...it looks like dried or peeling skin...but I just take a little alcohol and clean it up and reapply...it does hide the lace and seals good.Cheers
