Tiddler, well you and wet1 are both right.
Both surfaces reflect light.
The first, or outer face reflects about 10% of the initial light. The second layer is different as it will depend upon the color, shade of grey or shiny silver that resides behind it.
That 10% on the top layer will reflect all light and is the same amount when using either Gloss or Matt.
To make sense of that statement, remember the difference between Gloss and Matt is where the light goes, not how much there is. The light value is the same.
What the top layer application is doing is recapaturing directionally the 10% initial light power the Matt and color effect of the base paint scatters and absorbs.
Of note, that 10% loss at the surface will mean that the following layers have 10% less light to work with. Oh and it is a log loss beyond that.
What I am working on is a an easy roller solution aswell, although I am using the pearl metallic still. The main difference is that I am using layers, rather than a one thickness mix as the other formulations do.
I am experimenting with greys right down to N4 level, but I think I will end up around the N6 area.
