Protecting material from sun bleaching

[mr_vernon]

Is there something that I can spray onto a picture made of cloth in my conservatory to prevent it's colours fading in the sunlight?

Don't think so. If the picture is worth a lot, I think that there are special coatings that you can get on the glass though

if the picture is in a frame with glass there is a uv protectant glass you can use. i'm not sure if its actually glass or lexan but it does exist and it can be very expensive. Call a glass company.
