the laurel mt forge is easy and more forgiving to work with...it has some kind of degreaser built right into the formula so it more forgiving when handeling the barrels between rustings.....
Definitely forgiving. I was once building my young son a .32 caliber round ball m/l rifle and was using the Laurel Mt. Forge product to brown the barrel. On a whim I boiled a tea kettle full of water and poured the boiling water over the barrel, while it was standing vertically in a deep pan. It instantly converted the rust to a pretty, deep blue. My son didn't mind ...... he liked it like that, so I left it. What the heck, it was a half stock percussion anyway.
