Got my windows tinted today at Professional Window Tinting Inc. in Elkton, MD.
They are VERY PROFESSIONAL and HIGHLY experienced. They've been in the tinting business for 15 years now doing everything from autos to hospitals. They had over 15 different types of films to choose from and I ended up choosing a metalized tint by Diamond Automotive Window Films called "Radiant" in the 5% shade.
The owner and his son tinted my windows personally in about 2 hours and half. They told me straight up, tinting is not a race and it may take up to three hours and I agreed to this and waited patiently.
