I'm close to putting in the wood bed, some real good wood man told me to soak each board in Tung oil...that oil is very expensive..and he said "soak" ..then sand between the coats..before varnishing...how do yo saok a six by seven inch red oak board.? And I think I'm going to put down rubber runner where the folks will walk to the rear seat. thanks guys..Bruce D. mtvoices/
