Since it came out I've been using WD40 Specialist Silicone in my shop on some of my power tools (lathe chuck, band saw top..etc) and I'm seeing some rust.
Grandpa cheap prick,
If a gun or tool rusts, it isn't the fault of the gun or tool, or the potion that was sprayed on it.
It is the fault of the idiot that owns it.
More proof, right here, for everyone to see.
Did you ever get grandsonny that 5100 yet, so you two can watch it rust up together, or are you going to wait for him to divorce his third wife, and call it a combination gift?
Best,
Ted
