i've got a few j-frames and now that i think about it, my no-lock 642-1 purchased 8.8.8 is my favorite. also have a pre-lock no-dash 342 titanium cylinder airlite that was refinished in pd black by s&w and though it's in contention, the 642 edges it out by a hair (no shrouded bbl). i use hoppe's #9 on the cylinder and no problems with the frame finish.

both wear these grips:
