You will need to ask Tony or Erica which ever one is at the the field. For the most part we have to make everyone use our paint that way there is no "pay to play " and that is also how we make our money. Plus that is another way to control paint grade at the field. Not every paintball is made the same way and can stain our field. The paint we use is environmentally friendly and will not stain clothes. Hope this helps.
