Weatherstrip Care Tip
Weatherstrip seals are prone to drying and cracking—especially on older Corvettes. Regular maintenance with non-petroleum dielectric silicone grease keeps rubber seals elastic, prevents sticking, and protects against UV damage and extreme temperatures. Apply a small amount to a soft cloth and wipe over rubber seals monthly. This treatment extends the life of weatherstrips on doors, window seals, sunroofs, trunks, hoods, and convertible tops. Avoid petroleum-based products, which accelerate deterioration and surface cracking.

Because Details Matter
Whether you're chasing NCRS points or just chasing cooler temps, a well-fitted hood seal is more than a finishing touch—it’s a functional upgrade that supports airflow, reduces underhood turbulence, and protects critical engine bay components from water and debris.
