Here is some information I gathered about a year ago when I investigated this issue. Apparently, it makes quite a difference which film you use, and caution dictates a professional installation.
Kim
2000 Cab
Films available:
3M - 1st generation film had many fading issues, which prompted an upgrade in early 2004. The film still uses the same urethane, but a clearer adhesive. The old film also received many complaints about "orange peel" texture that made the film very visible on darker colored vehicles. 3M's new film is clearer, but is still behind in strength and clarity. 5 Yr Warranty
Avery - Film generally fades w/in 1yr and customer service is poor. The company has all, but fallen off the face of the paint protection industry.
Clearshield - Film's quality is very similar to 3M's 1st generation film, if not the same. Tends to yellow and crack in 2-3 yrs. Similar to 3M's 1st gen film, 90% of the adhesives will remain on paint when film is removed. 5 Year Warranty.
Llumar (CP Films) is one of the clearer films on the market. Customer service is lacking and company tends to work warranty claims based on the small print. Film's quality does not reject environmental oxidation, bird droppings, and other chemicals as well as 3M and Venture. Lifetime Warranty
Venture - film's clarity along w/ its patented acrylic adhesives make it the clearer film. Excellent customer service and film looks great on all colors - even black. Lifetime Warranty
INSTALLATION & SOFTWARE DESIGN
Film's quality is only as good as the installation. Searching out a good installer is not an easy task as many companies make outrageous claims of experience and expertise. The most important thing is to see what type of coverage you will get and whether or not it will be in one piece especially for the front bumper. Companies that use 1 piece for bumpers are generally more skilled at paint protection film installations, while software designers such as Clearshield, Invicashield, and Stongard created these kits for those DIYers in mind.
Below are some tips to searching out good installers:
-what type of software do they use. This will dictate their skill level as companies utilizing the 3 software pkgs above are used to having these kits come in multiple pieces for ease of installation.
-how detailed oriented are they........you will have to pick up these little signs while talking with the company or installer
-how long have they been installing paint protection
-are they certified by a film manufacturer? although certification is not a pre-req for being a professional installer, it does show that they received some type of training.
-can they do custom work with one piece of film. This is generally meant for those with aftermarket bumpers or would like to have certain areas wrapped that is not computer generated designs.
-if they do custom work, do they cut on the vehicle? For custom work, a template should be designed for the vehicle and then cut out on a drawing board. This will reduce the chance of cutting on the paint to zero.
-Ask if they use a heat gun to "soften" the material during installation. This is often a technique used by those not familiar w/ proper stretching of material..........this goes back to experience.
-Take a look at their work or better yet, ask for references.
