This stuff it like nails...so strong and powerful! But it says online to let dry for 20 minutes....no. I used it to mount a USB hub under my desk, and after an hour, it still fell off. But...without even adding more, I sat with my knee holding it in place for like 30 minutes....and now it's stuck like chuck.Make sure you have a caulking gun! That's the biggest advice I could give. I had prepped my table, cleared it out and turned it over to go to work installing my power supply and HUB, and then went to get Liquid Nails and couldn't get into it. Searching online, only advice said that my only choice was to wait on caulk gun, or to knife it open, use what I needed and toss the other 27 1/2 ounces! Well, I had prepped so dangit, I was going to finish. I popped my knee in the middle and put all my weight on it hoping that would get it to come out, and lo and behold....the bottom popped loose...so I was able to pull it the rest of the way off. So I dipped in from the bottom, got enough to finish the job and then put the bottom back on. I was worried it woultdn't be airtight or work right....but....given it's a comedy off error already of course I realized I needed more and had to dig back into it! When I went to remove the bottom the second time, it didn't want to come at first but I was able to realize I had a good seal and it was once again compressed with air! So today I ordered an extra large caulk gun, and next time I can save my knee for what God intended it to be used for...steering my vehicle ;).Since I purchased it, I've used it to fix a dislocated boot heel (normally nailed in, the glue has held perfectly going on five months...and I only intended it for a temporary fix), children's toys, a TV stand, and other odds and ends. When in doubt, I get it out....I'll never again be without.
