This pack of two 3 oz tubes ensures you have enough for multiple projects, providing a cost-effective solution for maintaining your vehicle's integrity. **Ideal for Indian Automotive Repairs** — This sealant is well-suited for the varied Indian climate, resisting water, weather, and vibration effectively. It performs reliably from -75°F to 450°F (-59°C to 232°C), handling both the heat of Indian summers and cooler conditions. While excellent for general automotive sealing, those needing a high-strength structural bond for critical chassis repairs might consider specialized epoxies. For cosmetic trim or weather stripping, this silicone sealant is a robust choice. Surfaces may require clamping for about an hour until firm. ## How to use 1. Ensure all surfaces to be bonded or sealed are clean, dry, and free from dirt, grease, oil, or old sealant. For best adhesion, lightly abrade surfaces if necessary and wipe clean with a suitable solvent. — Prepare Surfaces 2. Apply the sealant directly from the tube to one surface. For bonding, press the parts together firmly. For sealing, apply a continuous bead along the joint or seam. Ensure even coverage for optimal adhesion. — Apply Sealant 3. If bonding parts, clamp them together securely for approximately 1 hour or until the silicone is firm to the touch. Allow 24 hours for the sealant to fully cure before exposing it to water, vibration, or extreme temperatures. — Clamp and Cure ## Product details | Field | Value | |---|---| | Type | RTV Silicone | | Sensor-Safe | Yes | | Temperature Range | -75°F to 450°F (-59°C to 232°C) | | Resistance | Water, Weather, Vibration, Grease, Oil | | Shelf Life | 900 days (approx. 2.5 years) | | Application Surfaces | Glass, Metal, Plastics, Fabric, Vinyl, Weather Stripping, Vinyl Tops, Electrical Wiring | | Application Method | Apply to horizontal or vertical surfaces.
