Hi everybody. I was wondering, what sort of sound deadeners will stick on the door skins properly. My doors have been making a lot of flexing noises, so I stripped them down just now.

What I've found is that the inside surface of the door trims are made from some sorta furry chipboard/fibreglass composite. I am wondering if the usual sound deadeners (painted or stuck on stuff) will stick properly?

My ride is a KJ Ford Laser if that helps. Ohh is it advisable to remove the moisture barrier in the doors?

Cheers

In my suzuki swift i sound deadened the door trims, part of the trim was made out of a piece of 2mm chipboard. I used the stick on mats made by g-spot, haven't had any problems. Just be sure you clean the surface before you apply.

If you want to sound deaden your doors, you have to remove that plastic sheeting, is that what you mean?, no point in just doing the trim

we use sound off matting at work and have found it too be the best stuff for deading all car body parts ... only downside is not as cheap as some stuff but you get what you pay for ...

Hi SupaSwift. Thanks for you feedback. I've got no problems with sound deadening the metal doors. It's the kinda furry feeling trim that I'm worried about. So you recon' that it'll stick then.

What about the plastic sheeting. Did you put yours back after sound-deadening? Is moisture an issue?

I'm not so worried about the doors because my drivers are not in the doors. They're in the kicks. I was actually contemplating of fitting a layer of felt between the metal doors and the trim to further reduce the road noise.

Do you think I'll work?

i painted the inside of my door trims with black underbody tar deadener. it stank BAD for about a week, but it stuck properly and reduced road noise. to get rid of rattles in the door skin (like between plastic panels etc) i used blue tac squished in between. also a few strips of Flashtac here and there. nice and quiet now

you'd be surprised how many rattles come from the door trims, even though most people focus on deadening the steel of the door.

The G-Spot paint-on deadener is specifically designed for applying to the inside of the door trims.

Get it at Web Audio Direct, link from this site.

For the metal bits, inner and outer metal skins, G-Spot's Serenity Max is excellent, similar to Dynamat Extreme that I use ansd is excellent.
There are others.
Flashtac works on a budget.

But prepare the metal surfaces well with prepsol or similar first.

Thanks for the feedback guys. Just a couple more questions of your time if you guys don't mind ...

What's Flashtac?

How much G-spot will I need to sound-deaden two front indside of door trims?

[T-Bro]

flashtac is a roofing sealant used in the building industry. its basically a very sturdy and weather-resistant 'tape', that is simply a wide strip of aluminium foil, with a thick tar or bitumin backing. it is the tar in the tape that adds weight and lets flashtac act as a panel deadener.

flashtac is VERY similar to some brand name sound deadeners, especially 'Brown Bread' made in the UK and sold in jaycar stores, its just very slightly thinner but only barely.

i find that two layers of flashtac works wonders for panel deadening, and its nice and cheap compared to the big brand stuff, so you can feel good about going nuts

definitely worth a try, a $40 roll should do two door trims.

[basic124]

comparing prices on web audio direct, serenity (not serenity max) is better value than brown bread!! you get more of it for the same price (based on large pack), and its better (subject of many-a-debate)

hrm... thread hijack here..

i'm going to deaden teh inner skin of the door (not the trim) with serenity or something, but the panel side of the door frame, obviously its better to use sound deadening matting, but would gspot paint do anywhere near as well? i reckon i can afford serenity to put on the inside as well, btu i'm very lazy, and dont know that i'll bother myself to actually do the inside of the door... and paint jsu sounds so easy

so my question is, should i just use paint and make it easy for myself, or should i stop thinking abotu painting right now and jsut focus on matting the whole lot and using the paint for hard to reach spots?

or should i jsut paint the panel side and use matting on the interior side?? it seems soooo much easier!

i think you started to answer your own question dont be fooled by the fact its 'paint' though, sure it is, but it ain't like any other paint you've used before i can assure you of that. (depending how much you use) you'll need a couple of cheap brushes on hand, and gloves preferably, but out of the two the serenity is actually easier to apply imo.
if i were you, id use the serenity for the large panels, the paint for the hard to get places, and use the paint on the outer panel (with the door mechanisms etc) and put it on thick, but really i think you should definately consider the door trim, you'd be surprised how much noise/rattles it makes
