Framed Artwork

I have some beautiful framed artwork that I want to put on my patio. But its made for inside. Its a covered patio, so it will not be getting down poured on or anything, but still. Is there some type of spray or sealant I can get to protect it. Do you know what I found? You don’t say how it is framed, which makes a big difference. You could try to varnish the existing frame, but it’s probably not really suited to being outside. I suggest you have a water-proof shallow glass-fronted cabinet made and hang your framed artwork inside that. Something similar to the notice board cases that churches and community centres use would suit. That way, you can always move the artwork back indoors if you change your mind.
