A post pressurizing material treatment for bodies moving through fluid includes a series of compartments joined to the rear surface of the body. Each compartment is sealed by a top wall, a bottom wall, a pair of side walls and a front wall and is open at a rear end thereof. Each compartment retains at least one V-shaped base having diverging walls opening into the rear end of each compartment. Post pressurizing material is secured in a spaced between the walls of the V-shaped base for trapping fluid flow and accumulating forward pressure between the walls of the V-shaped base so as to reduce drag and propel the body forward.
