UV/light blocking film to protect collections?

[skyline]

Just wondering if anyone's had any luck/experience with UV + light blocking film overlays on their glass display cabinets? I have my fading pinks way at the back behind non-problematic ponies and in spots that don't get any sun, but I'm starting to get paranoid and was thinking of grabbing something like this to cover the glass windows. Or if anyone else has any other solutions I'm all ears! Just want to be able to see my collection without destroying it at all :/

Hmmm interesting question.  I'll be following this.

have you tried a car fitting place (kwick fit in the UK) they might have window black out film ?
