the smaller you go the more tedious it gets

Since I haven't been involved with p.o.p. for awhile in my past dealings with it
I found it best to try small blends of what ever glue or bonding liquid with p.o.p in a small batch to determine it's bonding characteristic,
as some may cause it to crumble.
I used plain white Elmer's Glue, then would seal it with Epoxy, for there are many different idea's on sealing after the mold curing.

Just a little insight what worked for me
