I'll chime in on this one also. I have been using this for years and have never had a single issue. I've resized thousands upon thousand of cases (both pistol and rifle) and never had a single stuck case (knock on wood). I leave my dies setup in my progressive press and never need to clean them out in-between use. With rifle brass,I stand up 400 pieces at a time in cheap loading blocks, Just as JGHOGHUNTER does, I intentionally spray into the case mouths at and angle down at the shoulder so the excess goes onto the body. I don't skimp out here. To me, more is better. I've never had any dented shoulders like I did starting out 20+ years ago with lube pads. I immediately start to run the press as the carrier dries in seconds. When I do high volume pistol brass, I put several hundred in the bottom of a small bucket I have and spray liberally while shaking. I fill up my feeder tubes with brass and go to town. It makes a progressive press run super smooth! The benefit to getting it into the neck is this keeps the expander ball from pulling the shoulder back out so the shoulder bump is spot on without the hassles of the dry neck lube powders that make a helluva mess! Imperial has it's place and I still use it but only for low round count loads and that's just to save my one shot!
