Every car needs to be washed the day before installation and garage kept, if possible, until installation. Please DO NOT wax. It is important to not wash the vehicle the morning of installation because water tends to reside in the rubber moldings making it difficult for the vinyl edges to stick in these areas. Our installers will then go over the vehicle with isopropyl alcohol to remove any grease or loose dirt before installation. Please note that any vehicles that arrive dirty will incur a cleaning fee.
