It should. The can states that it is for metal and plastic so I'd recommend just trying it and see if it works.
That's why I was (and still am) confused about it not working on the landing gear I painted with it. It should have adhered fine, but it didn't. The first time I sprayed the parts I let them dry about 12 hours and could wipe the paint off with my hand. I thought perhaps I had gotten it too thick or noat allowed it to cure long enough although I frequently keep going abter about an hour for it to cure. I sprayed it again and used thin coats with plenty of drying time and it did the same thing. I finally gave up and used some Krylon primer and it worked OK, so I don't know what the problem was.

Automotive primers, in my opinion. They are designed specifically to adhere to metal whereas model primers are designed specifically for plastic parts.
In most cases primers for metal can be used on plastic, but when in doubt try it on some scrap. Many primers are laquer-based and are very "Hot". They can etch the surface of styrene, but seldom do a lot of damage because the thinner evaporates very quickly. Any time I try something I've never used before, I try it on some scrap to see what it is going to do. This is especially true for automotive primers, and the only way to be certain you are using something safe.
