Back on the weathering and painting today. By the way, I am quite disappointed in the Testors 1214T yellow (spray). The paint takes a long time to cure and then flakes off. Much better choice is the Tamiya TS43 Camel Yellow - great paint!!!
Here are some pipes being painted in that color. Note the unique use of "T" pins I stumbled upon.
Here's a nice and dirty steel mill. I still have more piping to install and then it will get a lot of DullCote.
More when I know it.
