As is my wont, I will jump in to defend KJ against claims of lying.

Doubters claim he lied about oiling a surfboard, the consensus being that nobody would ever do that.

FWIW I don't surf waves, but I surfed the 'net and kowabunga, dudes, what do you know: oiling boards is not at all unheard of.

"How to Clean Your Surfboard

Soften the existing dirty, sandy wax that’s on your surfboard with sunlight.
Make diamond patterns on the surfboard’s wax with the serrated side of a wax comb.
Use the scraping side of the comb to remove most of the dirty wax.
Apply surfboard cleaner and let dry, then wipe down with a towel.
Use coconut oil to add further conditioning and an extra protective coat.
Re-wax your surfboard with a base coat and then a topcoat."

Alright lads, put that in your bongs and puff on it...
