Slippery Ramp?

This stuff works great in my back yard when the ground is soggy from rain and the grass/mud gets very slippery. I'm guessing it would work as well at the ramp (although I've never had problems with wheel-spin at any ramp)? I cut the 27 side in half and put a ~14" runner under each rear tire. This even works when I use the front hitch (which significantly inhibits rear traction due to about 1,000 lbs tongue weight in front of the engine) to push the rig slightly uphill.

They come up pretty clean and after one rain they look like this - ready to become a trellis?

This slippery 5hit used to frustrate me no end
