Will it dry clear?** A: Yes, this is Clear Food Grade Silicone Sealant. **Q: Is this real, odorless RTV, or does it have an acetic/vinegar smell like most silicone sealants?** A: I didn’t experience any of odor or acedic/vinegars smell/taste from this product. **Q: Will it seal a savino wine saving tritan plastic carafe? apparently the carafe is in two pieces snapped together tightly and frequently leaks.** A: Not sure about chemical burn issue. I manipulated the silicone around the hole in the carafe with a toothpick. The only caveat on the tube it comes in says - "Caution: On contact, uncured silicone sealant irritates eyes. Flush eyes with water. Call Physician immediately. Sealant releases acetic acid during cure." Acetic acid is the main component of vinegar. You could also use disposable nitrile exam gloves (usually comes in a box of 200) to put a barrier between your skin and the the sealant. I use those (gloves) all the time for stuff I have to around the house where I want to protect my hands but still have good fine motor control (impossible with regular work gloves). Good luck! **Q: I assume this is suitable to caulk around a kitchen sink and faucet?** A: Yes this fine around the sink and faucet in the kitchen. This product works very well. ## Frequently Bought Together - Silicone Sealant 100% RTV - 2.8 oz Squeeze Tube -Clear- - Silicone RTV 4500 Food Contact Safe High Strength Silicone Sealant, Clear (2.8 FL.
