I made a bit of an error move recently as I'm new to the hobby/game. A friend of mine who has well painted models recommended I get a black primer and spray all my models. Which I have done, about 1000pts of them and begun to paint them all. However, every tutorial I'm seeing online for Seraphon tends to use white or grey spray primer. I finished a warrior model, and I'm happy with the results, but I can't help think the colours would pop more with a white primer. Have I left it too late to re-spray all my models in white? or at least test it out on one warrior model then compare the results? What are all you guys using?
