## Questions & Answers

**Q: Does this dry to the touch or remain tacky?**
A: I put it one very thin so it is dry to the touch. I put it on the back of my boat carpet, worked very well but we'll see for how long after the summer.

**Q: my roof has a small water leak can i use this to patch her up ?**
A: I would only use it as a temporary fix. Assuming you know exactly where the leak is located on the outside. Water can travel a long way before it drips down. Fifty plus years of owning houses had taught me this.

**Q: What is the lowest outdoor temperature this product can be applied to Asphalt shingles?**
A: I wouldn't try it below 65 degrees F or maybe 60 F is the shingles have been in full sun for at least an hour beforehand.

**Q: Do you make a flex tip for tight areas.**
A: you can

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Helped me save a toilet tank with a hairline crack.
  

*by G***S on Reviewed in the United States on 20 January 2023*

This worked great to seal a crack in a toilet tank that was very slowly leaking. I sprayed it on and around the crack, waited overnight for it to dry up well and it worked like a charm, no more leaks. It has been done for over 2 months now and still no leaking. It saved me from buying another toilet.I also patched some loose shingles on the roof  and has held up well there too.

### ⭐⭐⭐⭐ 







  
  
    Decent product, but only worked for awhile
  

*by D***. on Reviewed in the United States on 11 April 2022*

Got this product to help seal around my skylights on my roof, it was easy to use,a decent price and seemed to work for awhile, but had to get back on my roof just to inspect things and it does crack,so I have had to try other products.

### ⭐⭐⭐⭐⭐ 







  
  
    Fixed the roof leak!
  

*by R***! on Reviewed in the United States on 20 November 2019*

I had a leak by the boiler chimney stack on the roof of our two story home. I was not exactly sure where the “pinhole” was, so I ordered two cans of Leak Stopper Rubber Flexx Leak Repair & Sealant Spray 18 Oz, and sprayed it all around the chimney area where is protruded thru the roof.  After a heavy rain we were happy to see, no more leak.  It “ Fixed the roof leak!”
