I know you can use the flake. Powder not sure. I have add pearl powder to d2 if I use it to coat the jig head. Used blue pearl in d2 on a black jig. Looks very good.
I do have some pro tech white pearl. It does have pearl in it. Not sure what kind of pearl powder they use. And if there are many different pearls? I have no idea.
But you have me thinking know.
