Question : Can I place this film over a bumper sticker to protect it?
Answer : Yup, I did it already and it worked great.
Question : Can I use this film to seal my leaking sunroof?
Answer : It should work because the film adheres to a clean paint surface very well. Try to buy a sheet that is 4 inches larger than the sunroof. Clean the surface well with alcohol before applying the film. Good luck.
Question : Is the measurement in centimeters or inches?
Answer : Inches.
Question : How long do I need to wait before using the vehicle with the film applied?
Answer : I don't know the official answer, but I waited overnight and drove it the next day as usual. If you used wet application, some water bubbles may appear, but they will disappear as the water vaporizes. After a couple of days, clean the surface and re-squeegee if needed.
Question : Can I use the film to cover a vinyl sticker? Is it waterproof and UV resistant?
Answer : Yes, you can put it over a sticker, but it won't be invisible due to its 6 mm thickness. It is highly water resistant, but I am not sure if it is waterproof. I use it on my MTB for paint protection at strategic points.
Question : Does it come with a squeegee?
Answer : No, you need to order an install kit separately. It's cheap. I recommend it for tasks like behind mud flaps or license plate mounting plates.
Question : What do you mean by 'the used one'?
Answer : Yes, it could be a big not run in looking.
Question : Can this film be used on hardwood floors?
