Permatex Flowable Silicone Windshield and Glass Sealer - 2EA - by Permatex.

Review: Very Good - This stuff is great, I bought it to seam seal my Lanshan 1 Pro and it did a phenomenal job, it's not thick and not to thin. and is easy to use/apply.
Review: Very good product used to seal car glass - This works. I used it to seal a leaking back glass on my car. Easy to apply and it dries fairly quickly. I cleaned the area first and then applied it around the glass seal from the exterior. No more water issues in the car trunk. Not messy to use. Quality product!

## Questions & Answers

**Q: Black silicone?.**
A: Clear glass glue for repairing cracks in glass.

**Q: Can you use this on small inside house window creaks?**
A: Not sure.... It's meant for sealing around windshields of cars....

**Q: Would this heal Scratch from washing sponge?**
A: Its not for scratches; it for sealing gaps around windshields and windows......

**Q: Are there two 1.5 ozs. tubes for $11.00?**
A: Yes I got two packages of the flowable windshield sealer. this stuff is thin and does a great job of flowing into the crack, the first time I used to much and it was hot out and the stuff ran down onto the windshield which after it dried came right off the glass with a razor blade. hope this helps
