Top coat with fine flakes?

Have anyone investigated the effect of mixing silver pigment or "silver-paint" with a clear translucent matt top coat and painted it on top of a paint? I guess what I am asking is whats the difference of mixing the paints as in C&S and adding the silver via a top coating?

Anyone tryed?

Re: Top coat with fine flakes?

i had contemplated painting a white basecoat and then painting a topcoat consisting of AAA fine and an orange pigment (for color correction) mixed in a clear medium.

i just never got round to it

Silver paint is too shiny to use as a screen paint unless diluted. The more translucent the mix is, the more the aluminum would manifest itself. It is a fine balancing act.

There is a screen mix supported on another forum that is simply a clear finish that contains 5% silver paint in it. This is sprayed over a semi-gloss white surface in many thin coats. Mech has tested this mix and while it has high gain, it also hotspots badly.

Another problem with mixes like this is that they are hard to put on in an even manner and one usually ends up with streaks or spots of differing reflectance due to uneven distribution of the silver on the screen.

Mix translucency is an area of experimentation that could yield great returns, but there are only so many hours in the day for testing.

Yes, indeed. WE do have the famous S-I-L-V-E-R which utilizes a 5% silver pigment top coat. Is that the same color mix that you Mech, denote SILVER in your GAIN tests?
