Well first off I wouldn't evaluate paste for a wave process. I would use solder bar instead.

Flux - top side fillets and no shorting on the solder side, does it clean well after processing if using water soluble flux. How wide is the process window in relation to min and max preheat temp/time, solder dwell min/max time and temp. Application methods spray, foam, dip? No-Clean or water soluble?

I would recommend that you re-post in the production forum as opposed this design forum.
