Priming question

THIN COATS! THIN COATS!  Are you trying to rattle can your primer?  Back away from the model, just back away!

If you're rattle canning, you should be about 1' from the surface of the object, and keep that can moving, both before & after you get near the object you're spraying.

Ok thanks, I was afraid that if I sprayed enough to completely coat it, then it is too thick.

I would think you want it to be a nice uniform gray coat. It will cover very well and if you are spraying so light that you can see the green still you may not have enough on.
