I would like info on your Dessert Moab varnish spray. I will have a black and white art piece printed on Canson 310 wt. GMS mat textured print paper. It is 59" wide x 42" ht. The framer has suggested mounting on archival foam core and float frame it using your Dessert Moab spray on varnish. I wanted reassurance from you that it will not yellow over time nor cause the piece to warp. If all that is a go, then I would like to ask about cleaning the surface. Thank you for your time. S. Jones

If you're framing behind UV protective glass then there really is not a need to spray your print. However, if you intend to float-mount with no protective glazing then the Moab Desert Varnish will protect your print from UV and will not yellow over time. Please note that hanging any artwork in direct sunlight is not recommended even if it has been coated with a protective spray.
