Review on EyeCatcher Tailgate Insert Letters Compatible With 2016-2022 Toy Taco (Bright Red) by Peter Nobles

I'm not sure I did anything wrong if only they aren't that sticky. According to the instructions, I wiped the dents very clean. I used a paper towel with denatured alcohol on it and wiped it down a few times. It was clean. Then I added each letter individually. I did this without touching the bottom, just the sides of each letter. I lined it up and pushed hard into the recess. Everything went well. It was in my garage and about 50 feet at the time. After 2 days of rain and my truck parked (about 35ft) I noticed the letters were starting to fall off. I'm disappointed. Now I'm not sure what to do? Buy a different brand or apply new glue to the back of the letters.
