Firewall treatment

Hey Team -

A quick question - I am installing my sound proofing today (faux hushmat) and curious what everyone does with the inner firewall afterwards? Do most go ahead and install the factory style sound proofing mat with the push pin christmas tree things or forego altogether?

Thanks in advance!

OK, thanks Keith. I guess what are probably a couple more stupid questions:
  1. When putting down the sound mat do you go over every square inch and cut out for protrusions like the seat hooks?
  2. After it's down do you then systematically go back through and cut out all the openings in the doors, floor and firewall?

Hope this isn't too basic but I want to do it right and I know there are probably many people on this forum who have done this and had it turn out well.

As always, thanks in advance.

You don't have to cut out every hole in the floor. Try not to put it over the seat mounting holes, seatbelt bolt holes, and your console mounting holes if you have a console. I like to use lizard skin on the inner doors and roof. Just my opinion.

I actually bought the lizard skin gun and was going to use on the entire interior but changed my mind. I just had nightmares of lizard skinning the outside of the car, my garage and everything else due to poor masking. Still haven't decided on what to put on the roof after spending 4 hours getting the original crap off which was a bit of a nightmare.

Lizard skin mixes like cake batter. You should mask off where you don't want it, but overstay is minimal. Water based too, so not much smell. I am sold on it. It also tightened up the roof metal. Absolutely no oil canning with it on. If your roof needs filler, the roof will stay put while sanding. I have no affiliation with the product, just happy with the results. I used the heat and the sound killer.

Re: Firewall treatment

Used factory mat, but also used a layer of Fat Mat beneath it where I could. Same with floors, doors, beneath rear side windows.. May not be as quiet as a new vehicle, but definitely quieter without all the road noise. So much nicer either listening to music or engine purr.
