How to remove protective film from shower panels

[Bryancbruce]

I've just realised after 5 years that my shower panels have protective film over them! (Often wondered why they would never wipe clean properly)

I've managed to remove a strip revealing the shiny surface below but the strip split and I now cannot find a new edge to remove the rest of it

Any ideas how I can get this off?


Thanks

Try working at it with the corner of a credit card.

Thanks for the suggestion but still no joy.

I had been remove the seal around the edge of the bath when a bit of the film came loose and I had pulled it off. The remaining fill just appears to be so thin and you can barely feel the edge with your fingers, I had been trying using a Stanley blade.

Someone mentioned putting duct tape over the edge and then the film might lift when it is removed

Heat gun but on low to med setting. the film should shrink at the edge very quickly without harm to the substrate.
