I just did a beadblast refinish on my new to me 659 and it came out mint, was SUPER easy to do and only cost me 25 bucks in materials including media and sprayer. It took longer to clean then it did to blast. Ten minutes blasting and half hour cleaning and i was able to erase 20 plus years of use (cosmetic of course). Now all i got to do is keep an eye out for more S&W 2nd and 3rd gen police trade ins and i will be blasting my way to a nice collection in no time. Now all i got to do is figure out a way to put up pics. Here are the before and after pics..........before is the one in box.
