Yes:
- **Hot-melt glue** — fast, strong, slightly melts the foam (good for fillets)
- **Polyurethane construction adhesive** (Gorilla Glue, Soudal Fix All) — strong, foams up to fill gaps, takes 1-2 hours
- **3M 77 spray adhesive** — for laminating sheets, repositionable for a few seconds
- **CA / superglue** — NOT for EPS (the solvent in regular CA dissolves polystyrene). Foam-safe CA exists (e.g. Bob Smith Industries Foam-Cure) but it's slower.
- **Epoxy** — works on everything, slow, heavy
For wings, hot-melt or PU is standard. Don't use solvent-based glues (contact cement, rubber cement) — they'll eat through EPS in seconds.
