Has Anyone Tried Car Paint Film Service in Mussafah? Need Help Before Summer

My car is only one year old but already has small scratches on the front. I park near a busy road in Mussafah and stones keep hitting my bonnet. Has this happened to anyone else here? What did you do to protect the paint?
A friend told me about something called PPF. He said it is a clear film that goes on top of the car paint. Is that true? Can you really put a film on your car and it stays clear? Will people even see it from the outside?
I went online and found a Car Paint Film Service Mussafah that does this. They say they use a special material called TPU. What does TPU mean? Is it strong enough to stop stone chips on the highway? My car travels on Sheikh Zayed Road every day and I always worry about rocks from trucks hitting my car.
What I also want to know is how long this film lasts. If I pay money for it today, will it still be working after three years? Or does the hot UAE weather make it peel off faster? I know our summers are very harsh and the sun is very strong here. Does the heat damage the film?
I also heard that this film can heal itself. Is that even possible? Can a film really fix its own scratches? How does that work? Does it need sunlight to heal or does it need something else?
Another thing I do not understand is the difference between PPF and ceramic coating. My other friend says ceramic coating is better. But someone else told me PPF gives more protection against chips and hits. Which one is stronger? Can you use both at the same time on the same car?
I drive a Toyota Land Cruiser. Is PPF good for big SUVs too? Or is it only made for small cars and sports cars? I also want to know if they cover just the front part or the whole car. Does covering the full body cost much more than just the bonnet and bumper?
What about the installation? How many hours does it take to wrap a full car in this film? Do I have to leave my car at the shop for a whole day? Or can I wait and pick it up same day?
Will the film change the colour of my car? I have a white car. Will the film make it look yellow after some time? I have seen some old cars with yellow film and it looks very bad. Is that a problem with cheap film or does it happen with all types?
Has anyone in Mussafah or Abu Dhabi used this service before? How was your experience? Did the film really protect your car from scratches and chips? Please share your story below so I can decide if it is worth the money. Thank you very much.

Consistency matters more than random speed in  fnf because successful performances depend on maintaining control across the entire track. Players who react calmly to difficult patterns usually achieve better results than those who rush through notes without paying attention to the song’s natural rhythm flow. 

PPF can be a smart option before summer, especially in areas with strong sun, dust, and road conditions. A quality paint protection film helps preserve the vehicle’s finish and reduce damage from scratches or debris. Many car owners in hot climates consider professional installation for better results.
