I just finished undercoating my car with U-pol Raptor liner, now I am going to spray the same in my interior and trunk. On the interior where I spray the coating I will be covering with sound deadner. My first question is where should I not coat/sound deaden the interior. I really would like to do the sheetmetal where the backseat rest (#1) on and the wheel tubs, but should I also do the small panel next to the tubs (#3) in the picture? It seems that if I did coat/deaden that area it would be hard get all the window bolts and cranks back in correctly, should I just leave this area in primer? Also, if I do the sound deaden the trunk should I put sound deadner on the inside of the rear quarters? How many people put sound deading material in the trunk?

Dustin, in my opinion you can never put too much sound deadener in your car , especially when you are at the stage you are on now.
Do area 1,2,and 3 by all means

I think sound deadening inside the trunk would be worth it to help keep out road noise and panel resonance.
