Here is the second backyard non scientific rust I conducted using some popular products. If you missed the first one it's here.
The testing parameters are the same except I didn't use any aluminum test media this time. I sprayed these stripper clips with Atlantic ocean water once a day for seven days. It rained on three of these days and for over eight hours on one day. I have been really busy working some overtime so I took this photo on the tenth day after the experiment began.
1) Control: Metal clip rusted over and corrosion starting to form on brass insert.
2) Eezox: Metal clip had two very small freckles of rust (one was between the S&Y on ASSY stamped on it) that I was able to wipe off with my finger without pitting. There was some discoloration on the brass insert which were salt deposits.
3) Boeshield T-9: Nail heads were rusted over and there was a small amount of rust forming on the left side of the metal clip. The Brass insert had salt deposits which wiped away and the rust from the nail stained it's left side.
4) WD-40: Maybe those who say that this is a good rust preventative will look at this. It is rusted almost as bad as the control and I feel that WD-40 has no business on a firearm to begin with.
5) Pro-Shot 1 Step: This is marketed as an all in one CLP. There was heavy rusting on the stripper clip and the brass insert is starting to corrode.
6) Safariland Breakfree CLP. On my last test this did worse than the old style CLP so I retested it again. Same results as last time.
7) Muscle Products PL-10 grease: I tested this because some of you use a lithium complex grease and asked me to test one. There was a little rust starting to form on the top left of the stripper clip and on the nail heads. The discoloration on the brass insert just rubbed off with my finger.
Like the first test I conducted, Eezox is still the best performing product at keeping rust at bay.
