Put Cordless Screw Driver To Hex End. With The Torx Bit Embedded In The Glue, I Turn It For Just A Few Seconds About 10 Revs Open Degrease To Very Very Shiny And Super Clean Moulds. Make A Second Glue Bullet, Coat Lightly With Moly Powder Do The Same, Then Turn Inside The Mold, Bullets Fall Out Super.
I Have Used Same Technique With Grinding Compound To Enlarge Mould That I Wanted To Open Just A Tad. Be Careful, Goes Quick.
