undercoating the inside

[94integra-ls]

I have a 92 hatch with a lsv and hasport motor mounts that vibrate a little more then I like and also I have some rattles in the interior that I want gone.i cant really figure out where they are coming from so I was thinking of undercoating the floor and back hatch area with undercoat or something that with keep the outside noise and rattles down.has anyone done this and if so was it worth it and how did you do it and what did you use and does it smell afterwords?thanks for and info you can give me

You would be better off with sound deadening material. Undercoat/bedliner is for corrosion and protection more than it is for any kind of noise reduction. Plus it won't take the rattles out of the plastic. Those need to be found and some kind of soft material needs to be placed between the two parts that are rubbing together causing the noise.

Did you buy solid mounts, or at least more solid compared to OEM? When I switched to 75A mounts, everything started rattling. I just got used to it.

Yeah 75a mounts and what kind of sound deadening would I use?

Stiff mount will cause some things to vibrate that normally wouldnt. Your safest bet is to use sound deadening sheets & matting where needed. Undercoating spray wont cut it.
