How does the self-healing work?
SunTek PPF contains a proprietary top-coat. This top coat protects the urethane against surface scratches. The majority of surface scratches will self-heal when exposed to heat – sun, warm panel (motor running), warm water, etc. We demonstrate this with a copper wire brush to simulate surface scratches that will self-heal such as surface dirt, sand, salt, etc.
Will SunTek PPF turn yellow?
SunTek PPF is protected against yellowing. Our top coat protects the PPF against harmful solvents that are in gas, oil, bird droppings, car exhaust, etc. that can absorb into the film and discolor it.
Will paint with and without SunTek PPF fade differently?
No. The area protected with SunTek PPF will fade at the same rate as the unprotected area.
Polarized sunglasses make PPF look iridescent. Is this normal?
This is purely an interaction between light reflected from car surface through the film and polarized glasses. Light reflected from the surface is polarized in different direction and each polarization propagates through the film differently. This is an inherent feature of the film as it gets oriented to some degree during the installation. A good analogy would be looking at a screen of an ATM machine in polarized glasses – you can see a normal screen when you look straight at it and then you tilt your head and see a black screen.
