I use the same brushes for coating kallitype and Pt/Pd. Just wash the brush thorougly after each coating and you should have no problem. Both of these processes use ferric oxalate as the light sensitizer and the addition of trace amounts of silver will have no negative effect on a Pt./Pd. print, nor will trace amounts of palladium or platinum negatively impact kallitype.
