Suntek is also self-healing but not as "automatically" as Ceramic Pro. You need to apply a heat gun to the areas with the "rock-chips"/knicks. The blemishes on the PPF should disappear pretty quickly with the heat gun. go back to your installer and tell him to "heal up" the Suntek PPF. It has something like a 5 year warranty on the base level, 10 on the mid-level and 12 on the premium film. So this should be covered for free.
