Amazon Customer 1 Worst product I have ever purchased but I guess you get what you pay for, although I've bought plenty of inexpensive products before on Amazon and not all have been this disappointing so it goes to show that sometimes it's the product. The adhesive is hard to apply and will not stick properly if you make the slightest mistake. It will take a steady hand and lots of experience to get this perfectly right, which I'm sure many will agree will probably not be possible by the normal person purchasing this inexpensive product. Unless you've done this a number of times and feel confident that you can apply this to your car without problems, then I would stay away from this DIY and let a professional do it.
