Use a majors good grade, not their low grade brand.
Yes primers have talcs in then but there are 1000's, maybe less of grinds and grades, not all are baby powder grade, thank God.
Ok, so when it comes to grades in talc, the finer grade they are the worse they are? I'm assuming its because they will absorbe moisture quicker? Trying to learn some technical aspects of it. Thanks
