I just bought this Made Rite brush today. The handle is obviously clear acrylic. The bottom says it is a pure badger brush and the knot is "set in rubber." I think it is a good candidate for restore, but I don't know the complete process. Is there a good tutorial on this forum I could use as a guide? I will probably go with a pure badger knot to keep its originality. This will be my first attempt at a restore.
