Most of attaching the warps isn’t so bad: it’s fairly straightforward, following Tim’s instructions, using thin CA and an applicator tip. But, it seems that if there’s any radial stress (stress perpendicular to the surface) on the warp when the CA is applied, there’s a chance the wrap will crack at that spot. Small crack, most likely, and no melting, but a crack. Cracks—tears, really—can also form from circumferential stress, along the surface, such as when you’re trying to stretch the wrap to help it lay flat.

If I was pushing a piece down, the chances of a crack forming were pretty high.

So, the leading edges of the protrusions on the Second Stage Aft Skirt wrap (the LH2 Fill, fairings for the LH2 feed lines, LOX vent cover.) aren’t secured yet. I’m debating whether to use some quick-set epoxy or thick CA. I’m leaning toward the epoxy, but the quickest set I have is five minute, and I want one minute. I expect I’ll use the same to secure the various loose wrap ends, but I’ll see just what happens after I attach the various tunnel covers.

I’m almost dreading applying the wrap covering the interstage between the S-II (second) and S-IVB (third) stages: it’s a tapered wrap. Maybe Tim has a different method for attaching, or maybe I’ll just go with the double-sided tape.
