Digital BW, The Print

Based in the UK, I made up this inkset using Opus Pro Dye Ink,and MIS Clear Base.
Have got some super results on both Ilford Smooth Pearl and Photo Paper Directs own Pearl Paper.
However the LK is fading very fast, in a bright room within 10 days.
I am assuming that the MIS base is incompatible with the ink.
If I could source Dye Glop from the same ink manufacture, does anyone know if this would work as a clear base.
An explanation for doing this is that I already had the Opus Pro ink on the shelf, and have used this ink in my colour Epson 1400, my own fade tests have shown no detectable fading after 24 hours in direct sunlight, also it is a very close colour match to Claria dyes.
Any ideas would be very helpful.
