If I am taking the gun out on a rainy or wet day I try and wipe it down first with RIG. Been doing this a long time.

I've been using Rig for a long time. I probably have at least 10 rig rags stashed round between the house, garage, vehicles & shooting bags. I only use it on the metal surfaces & have never had a problem with rust. I keep a rig-rag in the door pocket of my hunting truck so I can wipe my gun down as soon as I get back to the truck after I've been in the field.

I also use it on my better tools to keep them in top shape.

Same. I do like Clenzoil though.

I will use Rig on the metal, but I'm like Jay I like Clenzoil for everything,Rig is great for metal in the rain.
