My weekend project is to remove the backpad and rubber pad behind it. So far so good - the two combined weight 26 lbs! I'm going to put down some Dynamat Extreme and then lay a Morph carpet kit over the top.
One question. Do I need to remove all of the glue that is stuck to the firewall from the original pad, or do you think I can just lay the Dynamat over it? What should I use? So far I've tried Goof Off and a razor blade scrapper, but that's going to take a while and I already have a buzz going (IMG:style_emoticons/default/biggrin.gif) Attached image(s) |

Bad news, you have to remove it. Otherwise the Dynamat won't stick. If you sound deadening material is not 100% adhered to the surface it won't work like it's supposed to. Go get a bunch of 120 grit sandpaper and that will take most of it off. You'll have to spray some paint on the sections that sand down to bare metal. If the sandpaper doesn't take it all off you can try a wood chisel or a putty knife to scrape off the remnants. Clean the whole thing with alcohol or a paint-prep degreaser (PPG DX-330). And try to keep your hands off after degreasing. Skin oils will affect adhesion.
Brake cleaner or paint thinner will take off the old glue, but I've found that it makes more of a mess and is more of a hassle then sandpaper. You'll be surprised by how much comes off in the first 5 minutes of sandpaper. Take your time and be thorough and your Dynamat will last a long time. |
