Has anyone here had any experiance with mixing carbon dust to black gel coat?

does it work, or is it just a mess?

I'm planning on sprayin itand thought that it might make a nice look as compared to just plain black gel. give it a little sparkle of grey mixed in. sort of a look like using pearling only grey.

I'm guessing that with a 2.0 nozzel or larger, if anything it should make the stuff spray ok...I'm mostly wondering if everthing it scrapes on after dry turns black...I assume that buffing it would be a mess....Just figured I'd ask and see if anyone here had tried it before.

Best wishes
