removing sound deading from roof
 
I'm having one heck of a time removing the old sound deadening from the roof. Most of it was sagging and coming off, so I'm trying to remove it and replace it with hush mat.

You can see in the picture what I'm dealing with. On the right, you see what happens as you try to peel the stuff off. Some of the paper stuff stays adhered to the roof. On the left, you see what happened after I tried to use heat to soften things up. I also tried this 303 adhesive and decal remover (which is some really nasty stuff I'd rather not use anymore) and came up with similar results. Haven't tried goo gone yet. I'm thinking I might try dry ice next.

How thoroughly do I need to get the old adhesive off? I want the new stuff to stick really well. Any suggestions on removing this stuff?

I ve had great success with rubber attachment on drill like this one when removing old adhesives from inside of the car, rubber tire valve in drill works as well it just really small area of effect buut its cheap and always at home solution.

Is the textured rubber wheel like that one a lot better than the solid ones for something like this? I have a solid rubber wheel and it seemed to just smear the adhesive around. Maybe I didn't press hard enough. Also, I used the solid rubber wheel last night to start removing the gold pinstripe and it made an unbelievable mess of rubber dust. I guess I need someone to operate the vacuum while I work with the wheel.

If it's just sticky adhesive that's left I'd apply the new sound deadner right over it. As for the eraser wheel, the idea behind the slotted one is that it runs cooler. I watched a video that debunked it, so I'm still using a solid one with no issues. Every so often I just brush the dust away with my hand and keep moving.

Dry ice didn't help much either. At least it was fun to play with. The best I can do is scrape the adhesive to as thin a layer as I can with my metal scraper. I hope the hushmat sticks to it well.

I put the hushmat on with a roller, park it in the sun, then roll it again. The tar stuff is super sticky after it heats up. I'm pretty sure once you use any of the Dynamat type products they're on for life.

An abrasive wheel/rust removal wheel with a grinder usually works
