Removal of Gritty Traction Material

I recently bought a used epoxy longboard the deck of which is covered with a gritty almost abrasive material.I don’t know what product was used. I’d like to remove the material and use wax for traction. Any suggestions for removal of the grit?

…sounds like monster grip or ultra deck…uh, goof off will work,messy ,but will do the job.Herb

If it’s sugar coated (gloss resin sprinkled with sugar) you might try sanding it off.
