New patented grease that allows to eliminate the traditional oil from the tank of pneumatic spearfishing spearguns.
This grease clings at the molecular level to the aluminum of the barrel ensuring perfect lubrication and smoothness of the piston for hundreds of shots with relative increase in the performance of the rifle.
Thanks to the use of this grease and the consequent elimination of the oil, it is possible to load and unload the compressed air tank quickly and without the escape of the vaporized oil.
To insert the grease, the air tank must be drained, unscrew the shotgun head and remove the piston from the barrel.
Then insert the grease and then slide the piston inside the barrel so that the grease spreads evenly over the entire surface of the barrel.
For full efficiency of the weapon, I recommend renewing the fat once a year.
