Question for fellow members...

Submitted to Community Café

Good morning! I am working on my trash to treasure submission and need to tap into our community for experience and recommendations please. 
I sanded a skateboard and then put on Pittsbugh Paint Ultra paint and primer to seal the green of skateboard material.  I want to spray paint with Rustoleum over it, and when dry, do an acrylic paint pour over part of that. 
On my last project I tried spray painting over a different primer product and the spray paint didn't cover well. It kind of beaded up. Does acrylic work over Rustoleum spray paint? Do I need to seal with Painter's Touch glass spray after spray paint, before acrylic? Thanks for your help. Elizabeth
