Right then lol,
to build up strength in the enhancement, use build after bond and before boost................ you could use build 2x but buff lightly between applications, or your build brush will go cloggyfied and so will your build in the bottle........... then after that boost 2x or 3x for added strength........
Give this a go...............
Remember strength is in flexibility not in how ridgid the enhancement is.................
If it's to hard it can shatter or snap...............
just a thought
