I'm not an aeronautics engineer, and my last physics course was near 50 years ago, but it seems to me that anything you spray on the ball is going to effect the coefficient of friction, which would have to effect the drag coefficient. Surely something would decrease it- not to say that it would stay on or in any way be practical to use; a ball covered with oil of bitter almonds, for instance, might fly like a condor, but would raise other problems. I do seem to recall the question coming up with regard to golf- most efforts to influence air drag have been focused on diddling with the dimples, but I'm sure there was some sort of spray used too- PTFE, maybe- all of that stuff, naturally, being banned.

All I said was that it would have an effect, and that sometimes it would almost certainly be positive, which you don't seem to deny. Obviously there are more important factors, since curve will mostly be determined by air pressure. In answer to the original question (all of this has been pretty frivolous); No. Suck it up and play the match.
