5 Stars
Strong, durable and steel-like! Great price!
The price was great for this big size. Beats buying at a tool store.Got a small fridge where people in the office take it upon themselves to "empty" it of refreshing drinks. Got this JB Weld, a small latch and a spare lock I had lying around.I also had a spare thermal paste spreader spoon from a a computer build I recently did so I used that as my mixer. Right before I was ready to apply the JB Weld, I got a piece of cardboard and applied on the board both the bottles of equal length, separately. I then used the spoon to thoroughly mix the two until it came out in a consistent medium gray tone.Fridges have coolant pipes on the side of it so screws were a no-go. Instead, I used this Original JB Weld formula to keep it attached to the fridge. I installed in the the following steps.1. Emptied the contents in the fridge and unplugged it2. Let it sit for a couple hours so the water could melt into the drain pan on the bottom and then emptied the water3. Turned the fridge on its side4. Eyeballed where on the fridge the latch and hole should go5. Made a cross hatch of scratches with a utility knife on the surface of the fridge where the latch and hole was going to go as well as on the bottom side of the latch and hole itself. This allows the JB Weld to adhere and bite better on these items as it goes into these scratches and not just the surface.6. Applied JB Weld to the area on the fridge with the cross hatch pattern7. Laid the latch and hole in its open state so that the JB Weld doesn't adhere itself to the latch and its swivel8. Applied more JB Weld on top of the body of the latch and hole.If you apply too much you can also use a file set to file away the excess.Now, people can no longer feel free to my drinks! Tiny investment to secure my refreshments.
