How are you guys making and installing inserts for fuel tanks, waterboxes etc? I need to install all new inserts for both in my Rok, as my original install was an epic failure. I have some ideas, but I'd rather just do it the right way this time, haha. If I epoxy in some small tapped plates and glass over them, how would I keep resin out of the threads, and then remove the glass from over the threads? I feel like I'm making this way to complicated!
