Thanks for the additional tips.
I'm getting into this mostly for my Savage 110 that I lent out a buddy. On his Virginia bear trip this year he got rained on for 7 days and he did not care the the gun properly. So, my Savage which left the house with 95% blue in good condition arrived home with a couple dozed pin spots of blue worn off from water and surface rust damage. I can't see spending the $ on a full hot blue so am looking to...
1. restore the protection, and...
2. restore it's look a bit.
I think I'm gonna try the Blue Wonder and if it doesn't come out to my satisfaction I'll try the bake-on lacquer coating from Brownells.
My buddy already offered to pay for all the materials and help me with the process.
He's a childhood buddy and close hunting pal so I'm not gonna let a few dollars come between us.
