Just like Columbia4life said. Its a PK18 blended with the Activator resin.
Got this from the Lane#1 Forum.
From Mr. Buzzsaw Himself
"Yes, this is the first ever Lane #1 coverstock and the first ever Hybrid coverstock, called Hybrid RadioActive 18.
We mixed together the proven power and energy of the(Brunswick)PowerKoil 18 with the smooth, predictable, long lasting(Brunswick) Activator resin, creating the most powerful, versatile, longest lasting reactive resin coverstock on the planet."
