tricks to stop buzzing plastic door skin?

[tcguy85 10+ year member]

i deadened my metal door panels on my car. but i still have an annoying buzzing coming from a part of the plastic door skin. anybody have any tricks on what i could put on the back side of the door skin to stop this? i was thinking some expanding foam in a can, but some people have suggested against it. i know it would give the door skin a lot more strength.

See if you can find what is hitting/rubbing what else and put some bit of foam between them?

If its the actual panel vibrating, you could deaden it.

spray the back with a rubberized spray such as undercoating

I sprayed all my interior/plastic trim in my s10 with this stuff:

Never had any buzzing after doing that.

one person was telling me to go to a craft store and get some foam and line the panel with that. i don't want to use a butyl based mat on it, it's just to much money and i'm not sure it will really work very well anyway.

i actually just saw a new method the other day. use "great stuff" foam. i have not tested what it does to spl but it stops vibrations

Be careful with that shit, and best to get the windows and doors minimal expanding kind for small areas.

If your not careful and figure out why you should be, please take pics and share //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

silver backed peel & seal will do the trick and is pretty cheap. Mines been on for about 1 1/2 years and looks like the day I put it on. And ZERO vibrations...

Mass loading the plastic panel will help drop the resonating point. A spray like a spectrum will tend to help stiffen the panel more than a rolled-on mat would. You may or may not want this.

A more direct approach is to place a soft material between the two offending rub/buzz points so that even when they do vibrate, they bang aginst soft material, creating drastically less noise. A popular thing to do is to apply carpet backing between the metal panels of your car, and the plastic interior panels. Stuff it in there. Glue it up. Whatever it takes to pack it in. This helps with rattling, and helps with 'air born' noise as SS calls it.

If you want to get anal, do both methods. Mass load and stuff the panels with carpet backing or closed cell foam. I would.
