Excellent sealant for small repairs — clean to use and totally waterproof
I needed a strong adhesive sealant to re-fit a part on my carbon fibre golf trolley after some maintenance. This worked perfectly. It wasn’t messy to apply, it set cleanly, and it sealed and bonded exactly as I needed. Most importantly for me — I play a lot in the rain — it has held up totally waterproof. Really impressed with this for small outdoor repairs.

Clear, Reliable Silicone Sealant for Everyday Repairs
🎨 Color: Goes on clear and stays clear. Great for applications where you don’t want visible residue or white haze around the repair. 🔥 Heat resistance: Handles high temperatures well once cured. Suitable for automotive, appliance, and general repair use without breaking down. 😌 Ease of use: Very easy to apply. Smooth consistency, good working time, and cures without sagging. The tube dispenses cleanly and doesn’t clog. 👃 Odor: Typical acetic‑cure silicone smell, noticeable during application but fades quickly as it cures. 💧 Water resistance: Excellent waterproofing once fully cured. Ideal for sealing, patching, and moisture‑proofing around the house or equipment. 🛠️ Application: Bonds well to metal, plastic, vinyl, and rubber. Great for sealing screw heads, edges, and small gaps. 🏁 Final Verdict: A flawless 5/5. Clear finish, strong adhesion, great heat and water resistance, and easy application make this one of the most reliable general‑purpose RTV silicones you can keep in your kit.
