Review: Worked Perfectly! - Accurate directions provided and following them led to a positive result for me in fixing my cars passenger side door mirror. I was using gaff tape to hold the detached mirror housing in place, which would last a few months before totally deteriorating. It's an old car, a beater really, so I wasn't about to spend big money to fix this issue at a body shop. This provided me with a workable and affordable solution. Also, the repair looks so much better than the tape job I had going before! The RTV, once cured, has provided a super solid, and strong weatherproof bond. Great product!
Review: Works great - Works great to seal windshield that was leaking. Clear which allows you to make mistakes without it looking sloppy. Highly recommend if you have a leaking windshield or sun roof

## Questions & Answers

**Q: How long is required for setup? That is, the time you need to hold it together before it will stand on it's own?**
A: Depends on the temperatureThe warmer it is the faster it sets up. Figure on 15 to 20 minutes at least

**Q: Will this product bond silicone to ceramic tile?**
A: No

**Q: I need to reattach the rubber/plastic weather stripping on the outside of my windshield. Do you think it will hold?**
A: maybe. I used it to attach a tempered glass vessel sink to a bathroom wall, the glass base is 5 / 8 inch thick, and 20 inches wide. It is permanently attached You might need to use tapr to hold the weather strip in place while the RTV cures 24 hours or more for complete cure. Good Luck

**Q: Has anyone tried to remove this from ceramic tile after it's been stuck for a few months? How easy is it to clean up?**
A: It should be pretty easy to remove from the glazed, (shiny) surface with a razor blade scraper. But I doubt it will come off cleanly from the non glazed (rough) parts if the tile.

### ⭐⭐⭐⭐ Good option for glass art project
*by P***C on October 9, 2025*

Good product for my glass mosaic projects. Dries clear which is important to me. I wish the applicator was smaller since the size results in a lot of wasted adhesive for my needs.
