Polymeric mastic

[personaltrainer]

I ripped up the carpet/insulation today and will have to replace it but first i wanted to cover the floor and wheel wells with this stuff from www.mcmastercarr.com p# 9709T19 Hoping to get some better sound from the stereo as well as have less road noise and a more "solid" feeling all around.

Wondering who has used it and:
1.How much to cover the entire floor/wheel wells
2. How is this stuff compared to dynamat? - besides cheaper
3. Do i need a special roller tool to propery instal it or can I just press it down with my hands?

Thanks.

finally searched it. There is a sh#tload of info out there on this forum. This site has a great search function - some forums' suck! I'm a member of one that has a freaking google search in it for the search function - what crap!

Yup Im another one that coated the inside of a K5 with it.. Works good and is way more cost effective than Dynomat...

did ya'll coat the inside of the fenders with it as well? The part in the cargo area, you know what I'm talking about?

 

[daleearnhardt01]

I was going to but never got around to it. We made some new side panels though out of MDF and that improved the sound quality of the speakers I had in the fenders a ton...

my side panels are made of 1/4" plywood painted blk. The PO did this. To mount speakers in there is just asking for trouble, huh? The panels are a good fit though - SOOO.... I could just use theses pieces as templates to cut thicker wood - how thick is the MDF you used? In hindsight, do you think mdf is the best material for this? Thanks

I don't see why you couldn't use them as templates. That is how I made mine. I used 3/4" birch plywood though. I laid the stock panels on top of the plywood and screwed drywall screws in through the holes to hold it in place. Also, this gives you the exact locations for the holes. Fit perfectly the first time! Just remember the back part where the tailgate closes will have to be routed out.
