The product is great. I have had it on my truck for three weeks, going through a car wash twice a week. I check it every time to judge the adhesiveness and nothing has changed. The only downfall was the installation and that would fall back to the GM installation instructions. The placement of the strips is very difficult to mark out, but once you have that done it goes quickly.They look great on my 2014 Silverado 1500 LT Crew Cab and will do this again to my next truck!!
