I spent a good amount of time with the installer today going through the different films; I had samples installed on the car to view the differences side by side. Here is a recap if anyone is interested:
Avery Dennison Nano-Fusion
Relatively new product (a few years)
Comes with a lifetime warranty
Can wipe off marks with simple alcohol
Cannot be waxed, but has a really slick feeling after application similar to a wax (zero maintenance)
Slight gloss after install
Great puncture/tear resistance
Xpel standard (Extreme)
Been around awhile with good results
Can be waxed, but has a dull sticky finish without wax
Comes with a 7 year warranty
Marks will not remove with alcohol scrub
Moderate puncture/tear resistance
Xpel Ultimate
Brand new product (no history)
Can be waxed; has a smoother finish than the standard, but no where near the Nano
Comes with a 10 year warranty
Marks are removed with alcohol, but requires some elbow grease
Self-healing properties (similar to the Infiniti paint; after sun exposure scratches disappear)
Moderate puncture/tear resistance
After seeing the products on the car and letting them dry I am going with the Nano; finish is superior with a great smooth/glossy look. The Ultimate is tempting with the self healing, but the finish just isnt at the same level as the Nano. Only draw back is that he does not believe the Nano comes in a sheet large enough to cover the entire hood (he will call on Monday), while the Xpel can cover the entire hood. I prefer the lack of seams, so hoping that Avery has sheets large enough. Price wise the Ultimate is a little more than the Nano, while the standard Xpel is the cheapest. 3M is not in consideration after the installer showed me some pics of the yellow film after exposure to the Texas heat. Installer recommend the Ultimate for heavy track use, but I figured I could still tape if required and enjoy the better looking Nano while driving.
