That's a great question. Not every and all install companies install Xpel Ultimate. There are a variety of paint protection films out there so it depends on the install company. At it's basic concept, the install company should back the work they do, but also inform the customer that the film needs to be treated. All films need to be treated. Most of the time, as long as the film has been treated, it will last longer than the warranty is set for. With that being said, certian films come with certain costs. Xpel Ultimate is considered a highter end film and therefore gets more money for installing it. We typically install 3M Ventureshield, but we install Ultimate on request which was the case on this job. Depends on the area, but your typical package is a partial hood and partial fenders with sideview mirrors and front bumper. That runs around $600-750 depending on your area. Expect a 20% upcharge for Ultimate film. Then when it comes to full frontal, you can anticipate about double the cost since you are using double the film and it takes more time. Hope all that info helps. So if I were to guess, I'd say between $1500-1800. I know its a big gap but not sure of all the factors you are dealing with as I mentioned above.
