What this is: a clean, consistent four-stage progression — bare steel → wax primer → profile putty → wax wrap. Same framing throughout so it cuts together as one continuous build. Next pass adds cutaway cross-section slices + labeled callouts + the wrap-on motion.

1
Stage 1
Surface Prep
Bright galvanized run & branch screwed into the cast tee. Clean, dry, abraded steel — the SSPC-SP2 starting point.
2
Stage 2
Wax Primer
Translucent amber primer brushed over the joint zone — wets the steel and displaces moisture. Steel reads through the thin film.
3
Stage 3
Profile Putty
Pale grey-beige putty packed into the hub shoulders and crotch — fills voids so the wrap won't bridge gaps.
4
Stage 4
Wax Wrap
Non-woven wax felt spiraled over the joint and out each leg in overlapping courses — the continuous, conforming corrosion barrier.
Where this goes next
This locks the look and continuity of the build. Progress: ✓ crotch/underside wax coverage closed at the branch-to-run junction; ✓ cutaway cross-section built — see the layer cutaway →. Open items before the animatic: layer the callouts (step numbers, overlap %); stage the wrap-on motion course by course. The stills here are the keyframes those shots animate between.
