OK

pu2. Cheap tinting paper also has 99% UV protection. The thermal cutoff rate is a question of how much heat is blocked, which is literally an infrared part

pu3. Sunscreen is usually 99%, and UV protection works well in the beginning, but even 99%, it goes down over time due to durability, so it doesn't work after a year or two
