On glossy prints Lascaux is less effective (at least on a per-coating basis)
at reducing bronzing than is the Lyson Print Guard.

In my fade tests, the UltraChromes got a significantly increased life from
PremierArt Print Shield, which I suspect is the same as the Lyson Product.
(PremierArt denies this.)  The Lascaux did not improve UltraChrome
lightfastness as much (again, on a per-coat basis).

I doubt any coating can do this.

I don't recommend matte black with glossy papers, but some people have been
using them with sprays for some time.  With Photo K the sprays do increase
the dmax on glossy paper.
