Surface tension on small parts can cause the coating to be VERY thin.
I was told multiple coats with a very light spray is required to build up
the coating on small parts. Sharp edges are very difficult to coat.

Subject: [TN] UV can't see on the board
Hello,
The silicone conformal coating (UV added) was applied on our board.
All parts are well covered from both angles and were inspected under a UV
light.
All I need to have is just a small explanation of why the UV cannot be see
on some particular parts.
Any insight into this matter would greatly be appreciated.
