A 5 year warranty is standard on most kits but some manufactures give more. Usually installation is not covered under the warranty, just the replacement of the material by the manufacture.
Normal installation will take about 3 hours for the front bumper, hood, fenders and mirrors. Kits are usually offered in two or more sizes. Buy the large kit that offers the most protection.
You should be looking at between $750.00 to $850.00 but I have heard of some locations getting as much as $1,200.00 plus for the kit and installation.
Inspect the installation closely before paying. Make sure there are no foreign particles under the material and no work marks in the material. Small water bubbles under the material are common, they will disappear during the cure period.
A very clean work area is an absolute necessity. If the shop is not really clean and dust free, find you another installer.
You should be able to drive away after installation with no waiting period. Wait 24 hours before washing your car. It will take 4 to 6 weeks for the kits to completely cure, depending on the weather in your location.
If anyone has any questions, please feel free to contact me. I will be more than happy to share my experience.
