sound deadening
I have my door panels off to make some repairs to some cracks in the panels and lube up sticky door opening hardware. What's a good product for sound deadening that won't interfere with the internals?
I've considered stick-on mats and spray-on undercoating. Anyone have some experience/success with anything?
PS: I remember a thread about some fatigue cracking back there but I don't see any. Where should I be looking?

For durability and sound deadening in the back, I used a product called Bedrug. It took the interior noise level down a notch. For the doors and behind the panels, I would be interested in hearing what you guys recommend.

With the sound system that my wife has in her Aero, all ya got to do is turn it up and you can't here any noise. She runs enough power in the amps to power a small city, and with the 2 12" subs I can here her coming home when she stops at the stop sign a 1/4 of a mile away.

Just an update to share:
I installed the Dynamat(s) in my doors. Two packages of 5 12" X 12" mats was adequate coverage for both doors.
Before I buttoned everything up I did a visual inspection for fatigue cracking and found none. I greased the moving parts. I also repaired the horizontal cracks in the door panels that were just below the door locks just aft of the arm rests. I suspect that the plastic anchor "buttons" behind the panels were wearing out and allowing the panel to flex whenever the handle is pulled to close the doors. Has anyone else noticed this?
Everything is put back together. When the weather improves I'll see if the mats make a difference in the interior noise. It may not, but at least I got some deferred maintenance done in the attempt.
Still planning to flush that trans and install the external filter.....

I say to heck with external tranny filters. You still have to drop the pan, so you aren't gaining anything, and the burned friction material is still so small, it will pass right through the filter media. A good high quality filter inside the transmission is what the engineered have designed, and I just don't think an external filter does anything. It does have some risks too.

It's pretty obvious that the OEM filter doesn't do the job completely. Just look in the pan and magnet. What are the risks of adding an external? They have a bypass if it ever is needed. It should actually extend the service life of your existing pan filter.

Final update
Last update: the new Dynamat door project is not front page news but it is an improvement. When I close my doors they sound much more solid than they did before. Not that cheap rattling sound they always had. I think it's quieter but it's hard to tell because I still get noise around the door gaskets etc. Maybe something to make the rubber more pliable again.
One of those carpeted dash protectors might also help absorb some sound.
