Removing Dynomat tips?

[campindog]

I need to remove some dynamat type sound deadner to have some welding done to my car. Anyone have any tips or tricks to doing this? So far I've been using a heat gun and putty knife. I'm hoping there is a better way. This is making a mess but it is getting it done slowly.

Heat gun and a putty knife.

That is exactly what I'm worried about using this stuff.

I really don't think there is any easy way to remove it.

My shop removed Ll of the dynamat extreme from my car and use nitrogen to freeze it cold and scrape it. Heat was a nightmare they said and the colder it got the easier it broke the bond. Look into that

It's too late to try the cold, but if I ever have to do it again, I'll start there.

Thanks.

Dry ice works good!

I can't seem to find dry ice locally. Any other ideas?

had to do the whole floorboard on a chevyII what a nightmare. Good luck!!

Good luck. Interested to know what happens, although my thoughts on using Dynamat, or anything similar is that the car will hopefully be long gone before I ever need to scrape the stuff off.

One of these oscilating multitools with a scraper blade on it makes it pretty easy.

Acetone.

Thought I saw it in Mariano's but don't see it listed.

I used an oscillating multi-tool with a scrapper blade when I removed the mat from my floor.

Guys, when I had what was left of my floor boards and rear fender wells it had the 50 year undercoating on ( maybe old Zebart) I used a pneumatic "needle scalier" in the shade(little heat as possible) and the old undercoat popped off in small pieces from the vibration and scraping from the tool. Bought this tool at Harbor Freight and remember a pack of replacement needles is like 5 bucks. The body was on a rotisserie and where the sun hit it, did not work as well because the undercoating got soft. So after I discovered that I worked in the cool shaded areas and rotated the body and let the warm areas cool off ( and I had a beer). The Navy uses a HUGE version of this tool to clean the bottoms of ships. It may work for you....if it don't its a cheap tool anyway.
