Llumar or Trim-Line??

Hello, I have a question about disc tones.Which film has better UV protection and heat protection? Have the following offers for Chemnitz: Trim-Line: 308-340 euro Llumar: 250euro On the phone I was told that Trim-Line has better UV protection and the film could be removed without glue residue, for the purpose of reselling the car. What experiences have you made with the foils and maybe someone has a cheaper idea. Thanks in advance!!
