Here's what the description says:
"DesignaSeal makes a wonderful glossy top coat that designers put on
their hand-painted beads, Kato Polyclay™ beads, and over their finished
leaf sheet designs. Top coat can also be used as a fixative for dyed
beads."
I haven't used it so can't testify to the results, but I may get some with my next order to try it out. Worst case is I don't like it and won't buy it again.
