“I had hard adhesive / glue on the roof of my car. I was concerned that this disk might damage the paintwork and this item was going to be another waste of money. BUT I was wrong, this rubber disk smelt nice, it didn’t damage the paint, but mostly it removed the adhesive / glue. I had tried every other sticker glue removers and none actually work. This disk worked for me and the end result was shining paintwork and no adhesive/ glue. Good result for me;)”
