It's great these days to have all kinds of suspension, engine, trans, etc upgrades to make our old cars behave better. But there is one area where the old cars still fall way short. I would like to be able to drive my car in the rain, or go through an automatic car wash with NO leaks. And how about all those rattles... What kind of tips and tricks do you guys have to make the interior more livable?

Repo it, I have on several cars, new door seals, window seals and so on, tighten everything up including removing the dash, radio and heater or air conditioning I've done several complete ground up restorations and the casr drive and sound like brand new afterwards, including the new upholstery and carpet smell

Quiet cost money and time, but it can be well worth it. Modern insulation and sound proofing techniques, fresh seals, tracking down any components that rattle, resonate and knock; it's amazing how much some well spent time and money can acomplish.

How much time and money depends on how quiet do you want it to be. I put less than $500 worth of sound "reducing" materials into my 1970 ebody, plus the seals etc, and it's quieter than a lot of new luxury cars.

There is a limit though. The airflow and it's noisey turbulence around the car are somewhat fixed due to the design. The quieter the interior becomes, the more you hear the wind noise coming from just outside the windows etc.

Do you know how much weight the sound deadener added?

Noise reduction has become VERY important to the OEMs. Look at the new Challenger for example. There are seals between the door and fender! I'm sure that this was an effort to reduce wind noise.

You beat me to it - my 2012 SRT8 Charger has those seals - never saw that before. Near zero wind noise in the car and it has the added benefit of keeping the door hinge area a lot cleaner. I've been thinking about how can i incorporate that into my 70 Charger

I'd suspect that you could get a roll of a similar material and attach it to the back side of the door skin.....

No. I would guess about 30 or 40 pounds

Mine was leaking water inside because the cowl drain rusted out from being plugged. There was no easy fix for that one. Had to take out the dash and get busy cutting and welding. For the rest of it, the only other seals I really had trouble with were the windshield seal and the seal that goes between the front windows and the rear 1/4 windows. Best is just to replace all that crap.

The factory put on glued on sheets of plastic to seal off the doors and rear 1/4 areas. Better than nothing but doesn't really do a lot to stop noise. I bet doing the inside of the whole car with sound deadener would make a huge difference. Really, in stock form I didn't think mine was too bad in terms of road noise.

A combo of Dynamat Extreme and "The Insulator" from Aircraft Spruce makes a huge difference. Remember, with Dynamat you don't necessarily have to cover the entire surface to get the panel resonnation to deaden. Using less saves time, weight and $, but still gives you excellent panel dampning.

It's not the air filled foil you get at the Home stores, but a foil covered blanket sold for aircraft insulation at Aircraft Spruce called "The Insulator. It's great stuff, easy to work with and works better and cost less than anything I've seen for automotive use.
