The finished product is determined by the sanding done post spray. Turner's response is pretty accurate. I'm gonna test it on some spare pieces to get the look I want before hammering down.
Scott, I would use a painter’s blend technique where you fan the spray off at an angle at the ends of your passes.
This will gently disperse the texture off at the outer edges making the repaired area virtually invisible. I think using this method would eliminate the need for post-spraying sanding. The outer edges might have a little dry spray feel to them afterwards, but that’s not really a big deal because you’re going to be painting/dyeing the whole thing anyways. The paint/dye will cover the dry spray feeling.
Just a suggestion to help make the difference in textures indistinguishable.
