Re: insulating door and floors

it looks just like dynamat but just without the name on it. so therefore is looks like black tar with aluminum foil on it, i think it comes in roles, not for sure though. i dont know if i would put it on the actual door plastic was, but maybe on the back on the door panel or none at all.

Peel n Seal. Go to the roofing section of Lowes and ask for it by name. They will know what you mean. Also, I just did my car with it yesterday. Simple and quick process. Here are some pics of it

Well word to the wise, for it to do any good your going to want to put it on the metal actually causing the noise/vibration. Its made to kill the vibration on metal that cause noise.

Re: insulating door and floors

It is for heat as well as sound dampening. I did my whole car. Floors, sail panels, doors, roof, all of it. It is cheap enough to go all out.

Re: insulating door and floors

Peel n Seal in the roofing section at Lowes. Comes in 6" X 25' rolls for about $15 per roll IIRC. I did the passenger area and doors on my 89 with the stuff. I still need to get the cargo area and sail panels when I get a little more ambitious

Re: insulating door and floors

Is its thickness comparable to dynamat or other dampeners?

Re: insulating door and floors

Thats great I figure it will help take some of the noise out of the car and the price is right.Screw the dynamat!

It is pretty close. Plus it is cheap enough to do more than 1 layer if a guy wanted to.
