Bests & Worsts Reviews from Amazon

Works fine, but the can is stupidly difficult to open. The company doesn't even put instructions on their product on how to open the darn thing! I unscrewed the lid, and underneath was another metal piece sealing the top with the words, "cut open here." Cut open with what?! My husband said to use an exacto knife. It didn't puncture the lid, so I ended up having to hammer the exacto knife into the metal lid. What could go wrong with that! Three quarters of the way around, the lid popped off and chemicals sprayed out, hitting me in the face and eyes and all over my work table. Wear safety glasses when opening!) After a bit of time online, I found this: "HOW TO OPEN THE CAN: Unscrew the cap. There is a metal insert in the 4 oz, Pint and Quart cans that seal the can for shipping. This needs to be removed & thrown away. The process is simple: Hold the can to prevent the coating from spilling. Use a small screwdriver or ice-pick to pierce through the insert and pop it out. You may need to use a small hammer to tap the screwdriver to puncture the metal. " Hopefully this will prevent other people from getting this in their eyes and all over their face.
