Paint question and progression

Greetings all. I trust the fine people of the foam will be gracious and accommodating as they respond to this, right?
So, here is a pic of the (insert name tbd here). I'm headed toward paint. What you see is canvas stuck to foam with Oops exterior latex followed by maybe three coats of the same paint, was green and brown- very 'national forest' and that followed by two coats of glidden gripper. That stuff paints like 5-minute epoxy 4 minutes into the reaction
btw according to glidden a person can thin it with a bit of water. Which I did for coat #2
Stick with me here, I'll have a point, or question.
I was considering paint schemes, and as you can imagine I went through many ideas. And honestly I'm still not quite done. One of the options that I stuck with was a WWII fighter plane motif, but needed a 'silver' paint. Well that wasn't happening I. An exterior 'house' paint. So, while wandering through the big depot, like one does, the rustoleum catches my eye, but it's oil based...
I have sprayed their 'hammered finish' stuff on the frame with some success. The orange cloaked chap at the ready tells me the rusto- would be fine over 'gripper'
Almost at the point, stand by ( I'm putting myself to sleep)
So what paint to use? A couple of quarts of rustoleum blown through a cheep gun should work, but is that the way to go? Not many color choices, but I will manage. Or if there a better product, and by better I don't mean some diamond infused disco sparkle paint of exotic wonder, something I can grab at the big box store and blow on, or roll I guess.
And feel free to offer graphic ideas,
