My Rules
NEVER put orange dot on 3" flipper games . you will break the drop targets and damage plastics and many other bad things will happen . there is no need for these. as stated above there are several things you can do to "Liven up " your game .
It is ok to put orange dot on 2" flipper games I put them on most of my wedge heads .
