Ah protection... the stumbling block of a lot of the CLP products.

This test was simple, I took some spare SIG 229 grip screws, degreased them and treated them with...
-Breakfree CLP
-Militec-1
-Weapon Shield
-Gunzilla

I then put the screws into my T-Shirt pocket and ran on the treadmill for an hour, after which I put the wet/sweaty screws on a plate and let them sit overnight. I did this for three nights in a row. (Important note, my perspiration is VERY corrosive and has caused me endless trouble in the past with tools and firearms)

This morning I got the following results...

-Control screw: Slight surface rust in the slot and on the threads
-Breakfree CLP: Slight surface rust in the screw slot
-Militec-1: Distressingly heavy surface rust in the screw slot
-Weapon Shield: No corrosion at all on the screw
-Gunzilla: No corrosion at all on the screw
