had this annodized recently. Including it's origional anno, its been anodized 5 times
(the body). I had to machine a new bolt, upper tube was slightly oversized. Had to heli-coil the grip frame screws, threads were too loose. Other than those two things it seals up just fine and shoots like a champ.
Cockers are very forgiving when it comes to multable anodizing and tolerance issues. The only orings in the body that really need to seal are the valve, front block, and asa. All of those are static orings and you csn use dow 55 or a larger size oring if you have sealing problems.
