killing the sound

DickH · October 5th, 2008, 06:44 PM

So yesterday I went out and bought 3 cans of spray on rubber coating, 4 bucks each from autozone. I have removed about everything from the back seat back and there has been a bit of noise. I thought this rubber coating would help, I laid 3 cans down on it and am just waiting now for it to dry. Does anyone know how long it takes to dry completely, how well does it work, or if I used too little?

DickH · October 5th, 2008, 07:17 PM

iv always had good luck with that 3M sound deadning pad stuff, that spray on stuff can be sketchy

DickH · October 5th, 2008, 08:35 PM

spray on undercoating never dries completely

DickH · October 6th, 2008, 08:00 AM

is that true?

DickH · October 7th, 2008, 04:48 AM

OK well it has dried, or at least doesn't take fingerprints. It feels soft but doesn't rub off or smear so I think its ok. The sound is a little better, that or I just think it is because I know I did something to help it. It isn't to where i want it to be so I went out and grabbed some 3m spray on sound dampening rubber stuff. Maybe it will help, maybe it will just be it getting thicker I don't know. I don't know when I will have the chance but when I get my car on a lift I plan on coating the bottom too, mainly for rust protection but hopefully it will help that much more. What else can I do without spending gobs of money. Where on/in my car should I concentrate my attention?

Probably nothing. The dynamat types of dampening work great, but cost $$$ and tons of hours for the install. I did my entire truck and it cost about $500+ and took 30-40hours. It made a HUGE difference and i'd do it again for sure.

SteviGX · October 7th, 2008, 08:17 PM

your car's gonna smell like that shit for a good 2 weeks. I sprayed mine too with the proffesional undercoating...didn't really help all that much but my car smelled for a good 2 weeks

casper gt · October 7th, 2008, 08:43 PM

just put the interior back in, no more sound. by the time your done you'll have more weight in the undercoating than the interior.

casper gt · October 7th, 2008, 08:46 PM

oh yeah on the plus side putting the interior back in will cut down on the rice factor also

DickH · October 10th, 2008, 02:35 AM

update: Applied 3m spray on rubber stuff after the other stuff dried and it has made a huge difference. Well I am waiting for the 3m to dry but it is a lot better now.

SMSPerformance · October 10th, 2008, 02:37 AM

becareful what you get. some undercoating stays somewhat wet and oily
