One thing about our trailer is ,it's never had a car in it so oil and other liquids isnt a problem, we use it to haul our display around from event to event. Never thought of the spray in bedliner deal, Ron did you use a product like Hurculiner (do it your self) or did you have a Line-ex or Rino lining type of product put in? I had a pick up with Line-ex in it and that was some awesome stuff.
