## Customer Reviews

### ⭐⭐⭐⭐⭐ Good sealant
            
*by R***R on January 3, 2019*

Initial impressions are that this is going to hold up better than silicone.  Time will tell.  I like the fact that it will cure even at very low temperatures, though it does cure more slowly. For storage of the unused amount, wrap the tip of the cartridge with cellophane and store the cartridge in the fridge.  Keeps for months without hardening!Note: this urethane clings to your skin like nothing else -- it wipes off easy and doesn't feel sticky, but your fingers will be black for a week.  Guaranteed.  Nothing scrubs it off except time.
  

### ⭐⭐ extremly hard to dispense
            
*by M***C on August 21, 2018*

I don't know if this is the way suppose to be but I almost broke my hands squeezing this sealant out with a caulk gun! Very very hard - I was under impression that this suppose to be more in liquid form that will cure into a rubber seal. Not sure I will buy this again.
  

### ⭐⭐⭐⭐⭐ Incredible adhesive/sealant
            
*by T***. on March 28, 2018*

I used this to glue a fiberglass high top to my van.  I currently use no reinforcement in any way, this glue is holding it one with a thick initial bead and about a 1" wide backfill bead on the inside.  2k miles with no issues or cracks, great stuff!Do not get this on anything you care about, it has incredible bonding properties and is very hard to remove from anything that isn't smooth.  I layed a relatively thick bead and it outgassed for about 2 weeks where it was hard to stay inside the van for long.  After that the smell persisted but without the burning eyes xx.  1 month and I hardly smell it at all, just smells like a boat now.
