Zomby,
I don't know about the yellow lines,but it sounds as though the gun may have damascus barrels. I'm assuming that you've already taken the light rust off. Do you see a subtle swirl to the metal when the light hits at different angles? If so,it's damascus and should be browned. Brownell's sells a product by Laurel Mountain that will do this well.Once the old rust is completely removed.Polish the barrels as well as you can. Remove all traces of oil [they sell several products for this as well]. From this point on, don't touch the barrels with your bare fingers.Apply the rusting agent ,lightly and evenly, using a cotton ball in a clothspin. Allow them to rust,probably overnight will do,then sand using 0000 steel wool.Repete this until the desired level of brown is achieved. This should get the barrels back to near original color and will often bring the damascus pattern back out, at least to some extent.
You may wait and see if you get some other responses. Perhaps better ideas. But this is how I would approach the problem. Should you not like the end result, the process is reversable with a little more elbow grease.
Good Luck,
Jim
