I am deciding on whether i should get another layer of tint or not. I dont want to get another layer of tint and make it limo tint or darker then limo. I would just like to get another layer to get it dark enough but not as dark as limo so what percent should i get. Also does anyone know any negative side effects of a double layer tint? Or know anyone that has double layer that has been perfectly fine?
If you can't see your head unit's display with 15% tint then you need a new headunit.

But to answer you question, as long as the tint is properly cleaned you can layer it. The only problem you will have is being pulled over for illegal tint.
