So I did an experiment with both today. In the back I did one side with rustoleum truck bed liner spray can and the Hurculiner roll on. Wow the spray kind does ok but the can seemed to spray heavy and cause drips. It also is hard to work around tight spot and you have to do lots of taping off. With the roll on stuff man it's great. Easy to apply and you can really do one coat depending on how your using the back.
So all around roll on stuff is the way to go. Use the spray for touching up when you get nicks and scratches.
