I was really getting interested in this thread...especially about the Gummi Pfledge and the Di electric grease........and then became confused

. I have some of the Gummi Pfledge and it sure makes the weatherstripping look Great/New, but in the thread no one finished or came to a conclusion on its worth/value.....and also no comparrison with di electric grease was reached.
Questions please:
Does the Gummi contain any petro ingreediants rendering it harmful to weatherstripping?
Is di electric grease better (protection wise) than the Gummi? Which is more appropriate for protection and looks please?
If the di electric is better thant the Gummi, is any particular make (manufacturer) other than the Honda Stuff better than others. I have a giant tube of the stuff that I bought from Auto Zone or Advance but it is just some off the wall di electric grease....is this appropriate for use on weatherstrips?
I am just a novice and I hope my questions are not out of line....
Thanks,
Nic
Opps - forgot....303 is only mentioned briefly and not discussed. Is the properties of 303 not desirable? Would it enhance longevity of the weatherstripping to use 303 1st as a base for added protection and then one of the others on top for enhanced protection and looks?
thanks
