Should prints on Vibrance Metallic paper be coated to protect them from UV etc? I don't want to ruin the metallic effect by coating them if i don't need to..

Vibrance Metallic contains OBAs (optical brightening agents). They work by fluorescing in the UV range of light - not visible to the human eye. However that fluorescing makes the whites look very bright. By coating or placing such paper under glass, that UV component will be absorbed and not reach the OBAs in the first place. Result: not so bright whites. On the other hand OBAs eventually are destroyed by that very same UV. In time the bright whites will dull anyway. Try some BC Silverada. It's metallic and is OBA-free.

Good question. While photo papers can be coated with aerosol solvent spray coatings, we do not recommend coating Vibrance Metallic. Most people will simply frame their prints behind glass, and that is quite sufficient.
