Polywatch for 3ds Shell

Hi to all!!

I have a nice 3ds that works perfectly and overall is in really good conditions. The only thing is that is has some scratches on the shell and while minor I would love to remove them without buying a new shell.

Has anyone tried to use polywatch for this scope ? Do you think it will work ?

Also and not related… does anyone knows why the bottom screen seems to be peeling off? Do I need to replace it ?

Thanks a lot! 😬
