FrogLube's new bio-based CLP formula was developed to allow for professionals to transition between sub-zero conditions through high temperatures without having to change out their bio-based lubricant. The name "EXTREME" was coined during testing when it was discovered to work in every climate from -40F and all the way above +125F. FrogLube's new EXTREME is pourable in freezing climates and stays intact during high heat operations. Additional Benefits to standard FrogLube CLP: Remains viscous in sub-zero temperatures and does not evaporate or burn off during high heat. Reduced fouling on tactical rifles used in high volume round counts. Functions extremely well on "tight action" or precision built firearms. Can be mixed with standard FrogLube CLP?. Convenient applicator squeeze tube packaging. Complies with U.S. Army Field Manual/Tech Manual specifications for small arms operations and maintenance.
