I got a lowborn brush a while ago and love it. The original synthetic know was removed and replaced with a TGN either 2band or silvertip I really dont know. I love the knot that is in this brush. However, after going through many many pictures on lowborn site on facebook I found it. It was originally made june of 17. The sealer on the brush has pretty much worn off and I wanted to fix that. Is there a way to re seal it without removing the knot or damaging the knot? I've attached pics of the brush in question.
