Funny you ask, I recently asked the same thing! My Model 36 has bluing wear that is turned brown and looks ugly, so it was either a S&W Factory re blue or cerakoting. Re bluing is classic, but it will wear fast again. Cerakoting will not, so if it's a gun you're not interested in "collector" status which it seems like you're not since it was cheap, cerakote it. I'm going to because my Model 36 is my carry gun and it will get dinged, but cerakoting resists dinging and rust. The only people that would get mad about cerakoting are purists and collectors, but re-finishing at all lowers collector value so it doesn't matter.
