worth, especially red and black cars, remember after doing the Glare, don't wax your car and don't use carwash contains wax; otherwise, the glare surface will be damaged.
I did it from my present 1 and previous 2 cars in the past 5 years, the longest one can last for 20 months park indoor, for parking outdoor, it can last for 18 months.
If you choose wax, the best one is 3 layers crystal wax, noramlly around $600-800, if you park indoor, can last for 5 months, park outdoor can only last for 3 months or less.
Also, wax is harmful to car paint surface, so worth to do Glare or not, you decide la :)
