Allen: I think he uses a pine tree top for application. Just kidding as I would also like to know more about Brian's magic.

Brian, what are the stock dimensions?

1.5" and 2.5" with 14" lop

Rust bluing
 

What type of rusting agent do you use and do you have to vent the ribs with weep holes. That deep black color is awesome.

Mark Lees express blue.

If you use it, you will never use anything else.

Brian, how does one apply it?

Same process as any other rust blue, just no waiting between application and boiling.

So after the barrels are degreased, Do you have to heat them up or just apply the solution. Also is it Mark Lee Express #1. And are weep holes necessary? Thanks for sharing your knowledge.

A reading of the instructions from Mark Lees directly or brownells will anwer any questions that one may have regarding the use of the product.

I have found that the addition of weep holes is not a requirement for rust bluing. They just cause more problems than anything.

Thank you
