I'm working on repairing a rust spot in my floorboard & thinking about installing sound deadener/heat shield when done. Trying to decide if it's best to go with a stick on product like FatMat Rattle Trap, Peel N Seal from Lowe's or EZ Cool/Car insulation. So I'm looking at either a sound deadener with a sticky back or one that I have to use a spray adhesive to install. Any insight either way? Pro's, Con's? Any other products I should be looking at that are lower priced than Dynamat, etc?
http://www.v8buick.com/index.php?threads/cheap-sound-deadener-like-dynamat.260540/ I did this on my second car. First one was a ‘68 skylark that really limited road noise and drone. I haven’t had a chance to drive my ‘70 yet, but it was easy and cheap. I bought 3 rolls of it from Ace Hardware for $18.99 ea.
I used these type gloves, tennis ball and an old towel with my sneakers to contour/flatten. The dynomat foil will slice your fingers (paper cuts). Annoying, but not serious.
I got some peel and stick off amazon for my 65 ford and 69 Skylark . Works very well comes in different thickness same as dyno mat.
I asked my nephew what would be the best, He just completed a 12 year resto on a 70 Boss. As he explained, mat holds water, If you have just done a repair and it gets wet, because the mat will hold water , you will be doing it again, logical. I used Lizard Skin, water based, cures in one day and you can add the stock insulation with the carpet. I have just gotten done with the trunk and floors, done with the body off, did both under and the interior. The stuff seems really good and hides any repair marks.
I recently started replacing carpet in my '69 and found rust in the floor pan, so after hitting every square inch with a flapwheel and welding in a patch, I coated the entire bare-metal floor with Eastwood's Rust Encapsulator, then put down some lightweight heat-sound deadening mat I got off Amazon. About $30-$40 worth can do an A-body with leftover material. It has no asphalt and no self-stick, it's basically foam sandwiched between foil. Super easy to slice with a razor knife or scissors. I didn't do any spray-on adhesive because I wanted to make future removal easy. If this stuff turns out to be lame, it will be easy to replace it with "the good stuff." Here is a pic of it in my car, before repro carpet installation:
I used kilmat and loved the results, I put it on the aluminum door panels I made, and the difference in vibration before and after was remarkable. It's affordable and on Amazon
I used Flatline Barriers Floor Insulation and Sound Dampening Kit TABA1006 in the floor of my car. Summit had the best price at the time that I bought mine. Can't say how much attention that I have paid to the sound deadening side of things. It definitely cut down on the heat transfer from the M/T repro long tube headers to the interior of my car through the floor. The paperwork in the box showed it to be from PUI.
