I just used dynaliner on my roof skin. Didn't want to chance it. I wouldn't worry about it much as long as you made sure you laid it nice and clean. As far as the doors go i used strips of dynamat. I placed them anywhere that there was dip if that makes sense. I then dynalined my panels. I didn't want to lay a sheet on my doors in case i need to access my window.
I used dynamat as a vibration reducer and dynaliner as a heat barier. Look at my thread and you will see what i did to my panels.
