Let’s start by breaking dry time down into two categories:
- the amount of time before the customer can drive away
- the amount of time required for a full curing of the coating
Drive away time is the point at which the vehicle can be driven without damaging the coating. Air dry headlights at a minimum ambient temperature of 50° F for at least 60 minutes before the customer is allowed to drive their vehicle. We say “at least” because the exact temperature and humidity at the time of application may significantly increase dry time.
This time period can be reduced by using a fan, hair dryer, radiant heater, or heat gun to circulate warm air around each coated headlight. Turning the headlights on will also generate heat and speed up the initial drying process. Any heat source used should allow you to comfortably hold your hand in front of it. If it’s too hot, you risk damaging the coating or the headlight. After the first 10 minutes of dry time the solvent in the coating will have flashed off and additional heat will be of minimal benefit, but constant air flow will continue to aid in dry time.
