Is metal primer for the exterior supposed to be rolled or sprayed

[heeranyi]

I'm getting ready to spray paint the exterior of my bus and my question is I'm planning on putting metal primer first am I supposed to spray that on or roll it on and do I dilute it with anything

If your gonna spray the paint then spray the primer too.

What's the can say? Rustoleum primer says not to reduce more than 10%. It didn't like to be thinned- try samples first- some of them coagulate.

Read that can.
