I have 3 of these in stock with one having a dented can that I was sent a replacement for and didn't have to send back. The dented was sitting within arms reach so I took a peek. At first I thought I saw no adhesive but it's there. A nice smooth layer that looks as thick as it needs to be and no more. Nothing like the pic above.
