I personally have never used that brand of paint before, but yes, primering the body is key to a great finnish. After a few coats, take your sandpaper and knock it down a bit using a drop of dish soap in some warm water. (Go for the lighter grit) Dont sand to hard or you will have to break the primer out again. What your doing is taking the "eggshell" look off the primer before your base color coat. There are alot of defects on bare plastic that will bleed through no matter how dark your paint is. Primer hides these defects. Goodluck #James
. I would recommend the same type primer for same type paint. When airbrushing, alot of light coats are better than one heavy coat, Try not to hide or destroy detail while painting or sanding as this is very easy to do. I hope these tips help you out. Peace.
