Newbie who made 2 knives so far. So I wanted to try gun blue for some patina. Watched a couple of youtube videos and ready to go. Cleaned blade with denatured alcohol, put on gloves, heated blade with hair dryer as suggested and applied gun blue. Waited 1 minute then neutralized with water and wiped dry. AWEFUL....very splotchy, uneven and not very dark. Video said if you wanted darker repeat process. So I did and same disasterist result!
Try boiling the knives until they are hot enough to flash dry, apply the bluing solution with a cotton ball, when dry steel wool it lightly with 000 or 0000 steel wool and repeat until you get a rich blue, it will take several coats until you get a rich even color. Here is a picture of a rifle I did over 40 years ago with Birchwood Casey cold bluing solution. The rifle looks as good today as it did when I blued it.
When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!

Thanks Woods Walker. Had similar experience with my try at using vinegar. Cleaned blade, heated vinegar and let blade soak overnight. This morning it was black until I tried drying it off the coating came off too. I'm starting to get a complex! Any ideas on tjis one?
