After further research, via the internet, into the "primer" that I had the misfortune of using, I have found out that the primer contains fish oil! This ingredient is used to combat moisture and prevent rusting of the metal. With the fish oil, I don't know how this is going to work out when using Tamiya acrylics as a top coat.

Has anybody encountered or used this Rusty Metal Primer? It would be nice to know if I can spray my acrylics over this stuff, or if I am going to have to strip this Rusty primer off of the parts with more Superclean..
