C3 1978-1982 Corvette Door Panel Vapor Barriers

Protect your Corvette's interior from moisture damage with this Door Panel Vapor Barrier Set for 1978-1982 Chevrolet Corvette models. Designed as direct replacements for the original factory moisture barriers, these precision-cut polyethylene sheets install between the inner door shell and the door panel to prevent water from reaching the interior trim. Moisture entering through the window seals is directed back into the door and out through the factory drain holes, helping protect the door panels from warping, mold, mildew, and deterioration. Each barrier is machine-cut using digital patterns for an accurate factory-style fit and includes pre-cut openings for the door handle and lock rod. The window crank opening is intentionally left uncut, making the barriers compatible with both manual and power window applications.

Manufactured to meet or exceed OEM specifications, these reproduction vapor barriers are made from durable 10-mil polyethylene, matching the material used by the factory. The kit also includes butyl caulk/sealant strips for secure installation to the inner door structure, helping create an effective moisture barrier while maintaining proper drainage. Whether you're replacing deteriorated originals or installing new door panels during a restoration, this pair of vapor barriers helps preserve your Corvette's interior while maintaining factory-correct construction.
