Not all automotive window tint is made the same, and that goes for level of quality as well and for the actual assembly process, for the record. Take for example the comparison of Huper Optik ceramic vs 3M Crystalline window tints. The former, Huper Optik Nano-Ceramic window tint, is a film infused with ceramic particles measuring less than 100 nanometers in size (a nanometer is equal to one billionth of a meter) and that can help filter and/or reject various types of light. Ceramic window film is dye-free and metal-free, so it will not break down or discolor over time, never losing its efficacy or its aesthetic appeal.

Now, what does all that mean when you pit Huper Optik Ceramic vs 3M Crystalline? The latter product, a top-selling product from 3M, looks and works well when first installed, enhancing privacy and reducing the interior temperature of a car, and lessening the glare of sunshine and bright lights. But over time, those who chose 3M Crystalline vs Huper Optik ceramic tint will begin to notice some issues. As 3M window tint uses a dye layered over a window film, its coloration (or in fact its actual tinting, e.g.) can be scraped or scuffed off. This can happen over time due to damage from the elements, or in a matter of seconds if the windows are scratched at. Dye-based window film like 3M Crystalline is also subject to fading and discoloration over time, as sunshine, temperature, and other factors compromise its integrity.

While 3M Crystalline and Huper Optik Ceramic tints may look similar at first, time will tell that there is a definite quality difference.
