My question is I used mod podge to glue beads on a wine glass, but do I need to seal it with mod podge gloss?
most likely you will want to seal it either with that gloss you describe, or with an acrylic product called matte medium www.dickblick.com/
it dries clear and the stuff stays forever
Yes. You want to seal the work you put so much time into.
