I'm pretty impressed with this product so far. Take a look at the before and after of my 2011 Silverado. My dash wasn't cracked as much as some that I have seen, and I have tried to keep track and glue up cracks when they happen. You can see the black epoxy I used holding things together in the first photo. The DashSkin product is almost impossible to tell from the factory dash at first glance. 4 stars because it's not completely perfect, but it's darned close. Quick shipping, reasonable price, great customer service, and excellent instructions included (and online videos!) This thing was pretty easy to install. Follow the instructions exactly as they are written, put the glue dots and lines exactly where they recommend, and you will have no problems. I used shop towels and bricks as weights instead of a phone book as suggested in the instructions (because who has a phone book anymore?) Let the glue dry overnight and this thing is STUCK stuck on there. NO MORE RATTLING!!!! Seriously, this is the best part by far. All the rattling and squeaking is gone instantly. I highly recommend the one-piece product instead of the two-piece. The one-piece holds all of the parts together and keeps that second piece that's closest to the windshield from moving around, which is where most of the squeaking comes from. I have already recommended this product to a few friends who have the same truck with the same problem dash. I would definitely buy this again.
