Humm, I looked deeper into the technical documents around the matting agent, they state:
"Polyurethane Matting Additive will provide a reduced mar-resistant finish and therefore should not be used on walkways
etc.
When used with Perfection, the addition of Matting Additive will reduce opacity, hiding power, of the product, so it is
important that the necessary number of coats of unmatted finish has been applied first.
As with all types of reduced-gloss coatings, the finish will not have the same stay-clean properties as a full-gloss
coating."
Grim! Praps I'll stick with glossy and buy some better sunglasses....
