Window Tinting:
After a vehicle spends just a few minutes parked in the sun, traditionally tinted (dark) windows will store all the energy they can hold. The windows then channel the excess energy in different directions, superheating the interior. Tinted windows just block visible light and that might be helpful for glare and UVR protection, but if you're trying to keep the vehicles interior cool, it's not going to do much for you.
You should expect to pay more for a metallic film that will reflect light and keep a car cooler.
There is a misconception within the tinting industry that darker is better. The Energy Department recommends investing in the reflective coating, a more effective cooling technology. These coatings have a tendency not to be so dark so they don't attract heat
Manufactures have found that the colour charcoal will fade but won't turn purple like the grey/blue shades, in fact despite what the film companies are pushing as colour stable film all dyed product will fade. Only pure Metalized films with no dyes will not fade, ceramic films also fall into this category.
There is a new ceramic film being released in called Pinnacle'" and is clamed to provide UVR protection to 99.8 % and heat rejection of 52%, these are really high numbers for a light coloured film.
If you want lighter, natural looking tint in 35% range then 3MTN' is more of a smoke tint with some bluish hue to it and is quite reflective in certain light, it especially complements grey and silver metallic, charcoal coloured tints look great on dark cars.
A good way to check if you like the look of the tint is to take some film samples from different shops and stick them on your windows. Removal can be problematic but some Isopropyl Alcohol should take care of it. Picking the right installer is more important than picking the brand, make sure you get lifetime warranty on the tint and good warranty on the installation
After installation of a window tint film it can take up to three months for the adhesive to fully cure, a few air bubbles may appear, providing these bubbles are not raised (air pockets) they are areas of uncured adhesive that will disappear over time.
