I have started to play with the createx acrylic paint (thanks to the posters who replied to an earlier post). It is really great stuff, nice colors. Especially on my shoes where my airbrush cup fell off

I have in the past used all enamel and spray cans etc with a spray can sandable primer. My question now is, If I seal with the ceramacoat sealer, do people who are going to paint in acrylic, prime with an acryilic primer if there is one or use a spray primer or just seal and no primer just paint. Either with white as a base coat or just go with whatever color scheme you wish.
Thank you,
EricW
