I was able to get mine to work fine with win spp. I did clean up any flashing left over and lightly sanded the hole for the primers. If you haven’t, google vibraprime fix, there should be a few videos pop up for you. Win lpp do what you’re describing though.... Good luck with whatever you do. When it works it’s great, but is really frustrating when it doesn’t. Sent from my iPhone using Tapatalk
