Very excited.
I tried two other Ross brewing techniques before Mark Lee. I use the Home concoction with peroxide vinegar and salt. I also try to commercial brand which didn’t recommend heating. Neither matched this product. I stripped the firearm down to Barr metal again and tried this product and the results were in my opinion almost factory perfect. I filed directions, and I etched the pistol with black diamond under low pressure. I would highly recommend it as it is fast and very consistent results.

Mark Lee Express Blue no 1
I have been rust blueing for a long time, I've used most of the products available like the old Herters Belgian Blue and Dicropan IM and this product is by far the best of the bunch. You must make sure that the surface is clean and completely oil free. If you do that it will produce a very nice durable finish that exceeds any other products I've ever used
