Internal coatings are used to increase flow efficiency for natural gas pipelines and other anti-corrosion applications. Improved flow conditions may enable use of a smaller pipe or allow for lower compression requirements. Internal coatings are designed to improve barrel performance by creating a slick surface for the paintball to travel over. Some internal coatings are designed to also protect the inside of the barrel from scratches. This internal coating incorporates teflon and ceramic to create a hard and very slick surface. All barrels should be mirror/micro polished internally to say the least.
