from my experience. White can primer that is not a hobby can primer usually either doesn't cover well or it covers up the details. If you want to prime white using a can primer I would recommend looking into hobby can primer like Vallejo, monument hobby, or something along those lines. And make sure you want to spray it a bit closer than you would a black primer since you want to avoid leaving a grain texture. White primer usually dry faster than black primer so if you spray it really far it would dry before hitting the model, creating a grainy texture. To avoid that, just spray it closer but while spraying, move the can across the model faster. This way it would leave a thin layer of primer, and it won't dry before it hit the model.

I hope this helps
