i think Break Free CLP is "much" better, and these days it's all i use. It protects the metal a lot better than WD40 does
I gave breakfree a try once. I used it to clean and protect the bore of my enfield after shooting noncorrosive remington ammo. 2 days later I had rust in the bore. I did a little scientific test where I pounded several 16 penny nails into a length of 2x4 and coated each with a different protectant and left the setup outside for a week during the summer, Breakfree was the second worst protectant. The board has been sitting in my garage for 6 months and the only nail right now without rust is covered with RIG. I also tried Lee liquid alox as I leave that stuff int he bore of my rifles after shooting cast bullets.
My results were as follows:
RIG>Lee Liquid Alox>WD-40=BC Sheath>FP-10>Militech-1=breakfree= Hoppes gun oil>Remoil.
I rated them by how long it took for rust to form and the amount of rust. The nails coated with the last 4 rusted overnight with the rust on the remoil coated nails being somewhat worse than those coated with breakfree. The nails coated with Sheath and WD-40 showed rust by the end of the week, but not much. The nail coated with LLA showed rust after sitting in my garage for 2 months after the initial week.
YMMV, but I personally won't put breakfree near a firearm again, or remoil for that matter.
