Anyone use Porous coverings?

I've been reading and found a number of articles on the use of porous materials on the surface of square backed bodies that has a huge reduction in drag ( about 35%) due to the breaking up of the rear air rotation at the back of the vehicle and greatly increasing pressure at the rear. Any one tried this?
