I exclusively use D2T for my epoxy coat and frequently add glitter, the amount depends on the finish I want to acheive. The only recommendations I have are to get the smallest glitter you can find and if you thin the epoxy with DNA or something else the glitter will float to the top a little. It usually isn't enough to worry about but you can take an exacto knife blade and skim it over the top to remove the texture. Works great and looks good.
