yes definitely use rub...
after letting the injection work as directed, wipe off any on the exterior and then apply dry rub as usual...
Otherwise you'll do like we did at the AR a few weeks back and almost forget tp rub !!... Luckily Phil opened the pit 5 minutes into the cook to check Stoker probe position and noticed we had three briskets in the Spicebox without rub !!!
