I'm making a watch box that I will dye black with Tranfast wood dye. I'd like to follow up with clear glossy polyurethane. However, I don't know how to protect this finish because the dye's label warns of fading in UV light.
Does the UV light from fluorescent bulbs degrade dyes? If so, will annual polyurethane coatings protect against this damage, or do I need something stronger?
