1989 Honda CRX Si

I've got about a 1/2" layer of crap buildup that looks like it's about to morph into some living organism back there. There's also that factory soundproofing. I was sitting there, chipping it off with a screwdriver, but I kept scratching the paint (I'm repainting anyways). However, does anyone know of an easier way to remove the factory soundproofing WITHOUT chipping the paint?

I tried goo gone..I soaked the entire mat. That didn't work too well. It just made it a LITTLE easier to scrape up.

Suggestions?

use dry ice and a pool of rubbing alcohol. it will freeze it and then you can hit it with a hammer and it will shatter.

 

holy crap...that idea is awesome..i'm doing it tomorrow...

 

right now i could probably just go outside and hit it with a hammer, its so freakin cold.. -13F outside..

 

Feel yea there it was -25 (with wind chill) here in wisconsin the other day
