### ⭐⭐⭐⭐ 







  
  
    Wish it had come with a reamer/cleaner for the screw on applicator
  

*by C***N on Reviewed in the United States on July 1, 2022*

The idea behind using this adhesive was outdoor wood tiles.  See, the tiles are supposed to "snap" together and while you can get them snapped, they don't stay that way!  They slide apart every time you try to move the stupid tiles.  I mean I like them and want to use them but if they refuse to stay together, then they are useless.  I snapped together two tiles upside down and used this adhesive on the snapped together spots.  The box of wood tiles held 36-12X12 inch tiles.  What I wanted was a pathway in a dirt part of my yard and having the path 3 feet wide by 12 feet long works for my area.  So I will be working up two tiles at a time, snapping and gluing them together until I can make a 3x6 foot section and then another.  The slatted wood looks nice and still allowed water to drain down to the soil, yet keeps my feet off the dirt.  This adhesive, being waterproof is just what I needed for this project.

    It did the job.
  

*by B***G on Reviewed in the United States on August 16, 2022*

Used this to fill in the gaps for an aftermarket grill on my 10th gen Honda Civic Sport (on the top where the retainer clips are). Followed instructions and got superb results; the look with the front grill on it now looks very professional. RTV is not coming off unless I take a scraper or a pick tool and get it off. 👍👍

### ⭐⭐⭐⭐⭐ 







  
  
    Easy to use!
  

*by J***C on Reviewed in the United States on August 18, 2022*

I used this on my truck window (black rubber seal) what has had fallen and lessened the seal on the window. I affixed the JB weld, clamped for :60 minutes and it’s stayed through rain and 100º temperatures.Pros: ease of use, instant bond, long lasting bond!Cons: none
