so far I'm happy with the spraymax in the saucer, if I could do it again i would've cleared all the shooter, apron, upper arch, and saucer. I'm jaded with clearing the inserts because of ghosting. I know millions of play fields are cleared with no problems with inserts but the ghosting inserts are what caused me to go hardtop so I just sanded them and glossed them up with poly. i would recommend on the back side of the hardtop make sure all debris is removed from the clear parts of the insert. I thought i had mine clean as a whistle but after i was done little pieces of dust or debris magically appeared. I can barely see it but because I'm such a perfectionist I'm constantly looking for stuff like that.
With the actual laying down process i would recommend clamping right around where the snake head are and peeling the protective backing from the lower half just up to the 1000-Special inserts, lay down the exposed adhesive then remove the clamps and then peel the rest of the backing off and laying down the top.
When you're done you're going to chuckle at how easy it was. The biggest part for me was just making sure no bits of dust would get under the insert windows. Just take your time lining up the registration.
