I like to wire wheel (brass) where pinhole is,flux and solid core solder on leaking area.
A fresh layer of solder usually fixes it. If new soldered area is cleaned and solder flowed and looks clean after flux is wiped away you got a good repair.
Thanks, I get nervous putting heat on it, maybe weakening other areas. since I got it cleaned up well might just try a little JB Weld. If it works great if not then I can go ahead get it out of the car and let the guys down at the shop take a shot.
