Me personally, if the only option is you have to see through it, I wouldn't get it. If you're gonna cover the back and don't care, tell the guy how much work you have to put in to make it see through again and get it dirt cheap.
If the scratches are on the back glass and you stick something on the outside you will shill see the scratches
You can buy thin coloured acrylic sheet from a DIY hobby or craft shop
Cut it nice and tight and you won't need any silicon as it doesn't tracked well to sticking on acrylic
You don't find everything for fish keeping in a local fish shop you know lol
