Well, I'm still trying to figure this out. I've finally got the part
about the bonded layer being one molecule thick, although I'm still not
sure how that would work in the case someone suggested, of mixing the
silane with the gum and just coating and exposing. Sorry to be so dense;
I've been on Vicodin all week and am a bit foggy.

So okay, you would use the silane as a sub, and then you'd coat the gum
on the dried silane and expose it?
