UNDER THE STRAW HAT – Restorer’s Insight
On early C3 Corvettes, these bonding strips play a critical role in uniting major fiberglass components. Without them, your bodywork lacks strength and stability—especially during hood alignment and weather sealing. Use the correct press molded version for visual and structural restoration integrity.
