While the rust was sporratic, it seems to be only surface rust. The majority of it was removed with Striker CC (corrosion cracker) and 0000 steel wool. Now unless I point out a few minor pits the average person doesnt even notice. The real problem area was the grooved back strap of the grip frame. It seems to have a permanent brownish color to it now. But as Fisherman 48768 said, learning experience for me. The thing that gets me is after 2 years of owning the weapon with no problems this seemed to happen over night. I live in the south and there is alot of humidity. The gun is kept in a small Pelican pistol case, supposed to be air tight. The case is in an cheapo walmart gun safe. Parkerizing was a thought that crossed my mind. I really love the finish on the S&W 327 TRR8. That appears to be a park of some sorts, but I really love that deep blue S&W used to produce. I swear you can swim in it! Anyway, any other thoughts?
