Well, I am about to embark on my quest this next week to completely sound deaden my interior. Does anyone have any recommendations on how to lay the stuff? I bought a shop roll of Brown Bread (70 sq ft.). It’s enough for my car and probably my bro’s car as well (he has a 91 teg too).
Is it just peel, smooth, heat? Is that it? After I prep and clean the surface? Any tricks? Any help would be greatly appreciated!! Thanks guys.
dont know if you need heat for brown bread, but if you do, wear some gloves. burnt thumbs babee. try to get a hold of a heat gun too- heats much quicker than a blowdryer.
leave the edges of the door frame empty, so the panel can clip back in place. about 1/2-3/4" should do.
dont cut around holes, cover them up.
if you have enough, do the outer skin of the doors.
it doesnt have to be perfect. even if you just throw on a slab in the middle of a panel, it still helps. like at dynamat showcases, they have a desk bell, and with just a little piece attached it deadens the whole thing. course more would be a little better but you get the idea.
You need to clean the surface thoroughly. Use solvent to get any grease or dirt off or the material wont stick. do not put it on at night. put it on during a hot day. lay out the material in the sun to warm up and don’t attempt it without a heat gun. Heat guns are cheap and allow the material to form to the metal. Also most adhesives are heat activated. Rollers help out tremendously saving your fingers when forming edges and corners.
70 sq ft probably won’t be enough for your complete car let alone bro’s car. Small pieces will stop vibrations but do little to block noise. I recommend two layers on outside door skin and quarters, single layer on inside door skin, complete floor from firewall to trunk. rear panel can use two layers. rear wheel house are really bad on noise, they need two layers but the panel will have a hard time fitting. Don’t forget a layer on the roof. after that get some carpet padding(the automotive kind not home) and stuff in rear quarters and across floor.
