Best Way to Blacken and Seal Steel

Patricia,

Birwood-Casey’s Perma Blue (Gun Blue) works well on mild steel, and
they have a product called Super Blue that is supposed to work well
on stainless and polished steels. I have had good success with both
Perma and Super Blue on mild steel. I usually seal with Renaissance
Wax or Johnson’s Paste wax, although I think I am going to purchase
some gun oil and try that.
