I used this on my Remington 870 Express. I did the whole shotgun not just the barrel. Just be careful not to get it on the wood. Before I blued it I used the blue and rust remover made by the same company. Worked great. I didn’t use steel wool between coats. I just did what the directions said. After 7 coats the gun looked like it just came from the factory. It’s 35 years old and had a lot of rust on it when it was given to me. After I finished working on it the guy who gave it to me wanted it back. Sure OK. Not on your life. BTW. The whole gun only took me five hours and that included refinishing the wood with linseed oil. Wish I could post pictures.

I have use the super blue in the past and I found that it takes at least 10 coats to get a good finish. In between coats I don’t use water i use 90% alcohol to clean it and then steel wool and then clean it again and then apply the bluing. I do use a hair dryer to keep the Metal warm if you keep it hot seems to work a lot better not super hot just very warm to the touch. I have one barrel that’s over 20 years now and still going strong.

It has some pits because it had been neglected for 30 years. I probably won't use this gun. as I have no need for a 5th 12 gauge shotgun, so I'll check it again in about 6 months and rub a fresh coat of oil (my routine for the guns I don't use).

Steel wool didn't help. You degreased the gun of all oils and every time you put steel wool on the barrel you brought it back. Steel wool is treated with oil/anti rust to stop the hair like steel from rusting away while its sitting in the bag on your shelf. If you have to use steel wool, soak it in degreaser before using it and contaminating your barrel. It probably contributed to the splotchy look. Great topic and showing the work involved.
