Using anti-corrosive paint in plastic structures

Hello guys,

Many metalic structures (bridges, fuel/water tanks, cranes, etc.) are left sometimes wearing only their anti-corrosive primer paint coat. Most of the time it is an olive green tone or a dark red one. I just bought a spray can of the green type to do some maintanance to my aquarium chiller, and I was wondering if I could use that stuff on a plastic model of a crane bridge, and give it the look of the real cranes I’ve seen. I’ve also seen locos wearing patches of these kind of paint. Can I use it? or is it better to buy a model paint like floquil or testors?

Test it on some of the sprue from the kit. Some petroleum based paints do attack styrene plastic and turn it into jello.
