This is a nice thing to just set down on your layout to create a whimsical or authentic period atmosphere. All of the things we couldn't figure out what else to do with eventually become a pile of rust. I like the fact that it is already painted a uniform rust color--ready to use. You could add more detail variation if you wanted to.
The mold is nice, the details are fine
uniform color, even if the model reproduces the rust diminishes
a careful and patient coating allows a good result
