That air bubble is in the pit fill, the repair is filled nicely. Above or below with the pit fill, they both work it is all in how you roll the film on.

I would not use that UV "shield"? for any slow filling star breaks,or on sunny days,or at all.
Do yourself and customers a favor and don't let in any UV until you are ready to cure.
