pigment has nothing to do with uv protection.
Everything shine posted except the last sentence I accept.
Urethane clearcoat offers little UV protection. Generally when a manufacturer informs you a clear has UV protection it will have added a UV tint to it and they caution the tint will affect colors such as white and yellows by shading them with a slightly brownish look in their tech sheets. Sikkens is notorious for this effect and requires that every paint job unless a complete paint job is to be performed to blend all work.
