Ballistol does not resinify. Most other lubricants are subject to relatively fast aging and oxidation. They harden in time – a process which is called “resinification.” The oil begins to thicken, becomes sticky, gluey, and finally turns into a hard resinous substance. By contrast, Ballistol contains a combination of anti-oxidants and medical oils, which together make it much less susceptible to the process of aging than other lubricants.
