I had a Fiskars trimmer and no where on the packaging did it mention a removable protective fillm. My surface started to bubble, so I contacted Fiskars and was told about it. I felt stupid! The surface of my trimmer is not shiny at all. I don't need the swing arm for cutting A2 cards - maybe you could try this triimer?
I like the fiskars trimmer because it has a wire & it is easier to see exactly where I am cutting.
This trimmer was less than $20 with a coupon at Michael's.
