Gary,

Renaissance wax may well be the cat's meow, I can't say, but I have used both ones you mentioned, and they work fine. I'm a duck hunter, and my guns get subjected to less than ideal conditions at times. Johnson's Paste Wax does a good job of protecting the gun from the elements.

I would tend to say I favor the BIrchwood Casey for luster, the Johnson's for protection.

May God bless America and those who defend her.
