I posted last week about using either axle grease or vaseline to help "hold" the paintballs that I shoot off of golf tees in place - especially when a near by hit might knock the unshot ones off.
It turned out to be a windy Saturday and Sunday so it was a good test day. The axle grease was just too messy, I forgot to buy a glue stick and the vaseline worked great.
I found that just a dab holds it fine and if you put a little more on it will some times leave a part of the paintballs shell.
Those make for some fun shots!
