Greetings. I'm new to this site and am hoping someone can help me out. I'm attempting to rust blue my Winchester 94 and seem to have a problem. Following the AIG video, I degreased the parts, heated with a hair dryer, applied the first coat of acid, followed with the second 2 hours later, let it rust for 8 hours. I had a beatiful red rust. I boiled the parts for 20 minutes and got the black velvet look I was expecting. After carding everything looked very nice. I really thought it was going good. This morning I applied the 3rd coat, let rust 8hrs, boiled for 20 min but the parts still looked rust red. I'm fairly sure somethings not right. What did I do wrong? I could sure use some advice.
