I did this yesterday as well and I also have side cameras. It was stuck on really tight. What helped me was using a hair blow dryer to heat up around the reflector from the outside. I bet this can be done easier in hotter places. I did it in the morning and it was around 65 degrees.

One suggestion I have is that once the original reflector is out, when you are ready to stick the new one in, you can put the painter reflector in through the empty hole instead of through the wheel well to minimize the chance the glue touching anything.
