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
This often-overlooked rear seal plays a major role in maintaining a leak-free, rattle-free convertible driving experience. Replacing it restores the critical factory barrier between your Corvette’s top, glass, and deck lid.
Under the Straw Hat – Restorer’s Insight
On C4 convertibles, the rear body lock pillar seal is uniquely shaped to contour the convertible’s roofline and deck interface. Don't confuse it with coupe seals—this part is convertible-specific and side-specific for correct fitment.
