Here you go [MENTION=51599]The Heater[/MENTION]: http://www.dynamat.com/technical_installation_door_kit_install.html Official dynamat instructions. Look at optional step 4a and notice they work through a hole in the door just as I did. Also notice they call the surface to which the material is being applied the 'outer door skin'. I'm using the same terminology as the manufacturer for the very same step and method the manufacturer uses. To use your own inflamatory words, "you would truly be a moron if you thought" I was using the term 'outer skin' to refer to something other than the very door surface to which the manufacturer refers when using the term 'outer door skin'. Surreal P.S. I'm pretty easy-going, usually. However, you've made several inflammatory posts (it's word choice, mostly) and since you like using those sorts of words with others you clearly also don't mind having them used with you, as the golden rule is to do unto others as you'd have them do unto you. Have a nice day, I'm done here.
