Ok, so we all know that paintball fields have restrictions on certain paints.  Why are these paints restricted?  There are multiple reasons.  The most common and a major reason that paint is on the banned list of your field is the paint is probably oil based.  As paintball has progressed, we have experimented and found out water based paint is much better to shoot off.  Not only do oil based paints destroy/stain the fields property, they do the same to players' gear and skin.
