Pros : Creates lovely pieces that can be used as pendants or decorations.
Cons : None so far.
Other Thoughts : Used Hi-Fire Hotline Shelf primer (failed to find the recommended Primo at the local shop and decided to try what I had in hand) and a small painter's brush to prime the mold, applied 7 or 8 coats. The fused thing dropped off pretty easily and the central post stayed in place.
You really need to prime all curves carefully, especially around the post and the central "hook".
