I guess I'm just lucky. I just don't to seem to have many problems. I've never owned an inline that wouldn't shoot pretty much the first thing (and anything) I put down it very well. I've never seen stainless rust. I've never had any pitting. I've cleaned with hot water, soapy water, tepid water, coffee, windshield washer fluid, Windex, and saliva. I've tried about every lube that you can buy and invented several myself. I've never even seen a scope or mounts that couldn't be cleaned up with a few patches dampened with Windex. I don't even remove the barreled action from my stock when I clean the gun. Should I be concerned?
