Hello everyone! I currently make blue, green, and purple antiques by mixing Angelus dyes into Eco-Flo Smoke Black hilighter. (I have tried mixing them into Fiebing's neutral antique paste also, but that leaves this horrible chalky finish.) The effect is lovely, but lately I've noticed some terrible fading. The kicker was when a suit of armor I made faded from green to brown while NOT in direct sunlight! I've tried using the Fiebings alcohol dyes instead of Angelus but they seem to be fading as well when left out in the sun.
Do alcohol based dyes always fade with exposure to UV radiation, or is there something I can do to prevent it? I have tried Meguiar's gold class conditioner (has a UV blocker in it, supposedly) but it didn't help.
What bright-colored dyes or stains do you know of that behave better in the sun?
