any chemists here?

The oil pressure is fine. There was a decent amount of overspray on the valvetrain, and a certain someone is stating that it will clog his oiling system. All my machinists and many fellow mechanics state that it will take ALOT of paint to MAYBE clog the pickup screen. Nothing has gone wrong with his "tired" engine. He is basing his case solely on "assumption". I have never seen the car since it left, just pictures.
