:iagree: :iagree: marine version is probably stronger.Al-53 said:Sparkie...I am not sure if the same.. they might be....but I would call DG and ask them...I would think they are very close...just remarketed for different application..one a car and one a Marine and RV....or the marine version may be a bit stronger....I think DG would have a better answer..email them and see what they say or call
