The aircraft was enroute from sheboygan falls, WI (sbm) with kojc as the destination. The pilot selected full flaps for landing on runway 18 at kojc, which had just received a heavy rain storm. After touch down, the pilot deployed spoilers and applied the brakes as the aircraft began to hydroplane on the wet runway.
