Dear Gail and Gretchen,
I am sure any paper conservator worth their salt would have conniptions over such treatment!
It has to degrade the artwork and lessen it’s life. Worst of all it wouldn’t be reversable.
If they really can’t afford to frame it and want to be able to see it, perhaps a sealed Mylar packet is an alternative? That would have to be done professionally by a conservator or conservation lab.
It too would change the appearance but is reversable.
Tell them never to laminate as that is even more destructive.
In the meantime storing in a metal drawer or an archival box between sheets of acid-free tissue is the best option.
I would do what Patricia suggests, using UV glass or plexi to prevent fading. Advise your client colors will last longest out of direct sunlight. I have never sprayed watercolors. I have, however, heard of people doing that instead of glazing. They spray both sides with fixative, then coat with a UVA varnish. I can't imagine doing that to my watercolors. I would think you'd lose some of the delicacy of the media.

I just finished and shipped an unframed watercolor painting to a client in North Carolina; she asked about protecting it from humidity. Is it recommended to spray it with a fixative or varnish of some sort? and if so, should it be put under glass or UV-resistant acrylic or left without a cover?
The piece is on Arches 300# and was painted with Daniel Smith watercolors. Since it's already at the client's, not knowing if they have access to someone who knows how to handle artwork or not, can they do the spraying? Front only or both sides? # of coats, etc. In other words, any info you can give me will be appreciated.
