Suggestion on removing Dynamat material???

Howdy boys, last year before round up I put a temopary notch cover over my rear end in my truck. It was not anything pretty just needed to try and keep the fumes from coming in during our road trip. I am now in the process of removing the cover to re work the wheel wells and I would like to redo the notch cover now that I have time. My question is does anyone out there have any tricks to removing dynamat style butly based material??? It is the stickiest crap on earth and it is taking for ever to get it off so that I can start rebuilding. Anyone of you guys ever removed this stuff??? ANy help is appreciated!

Just start peeling. It sticks to itself well but will not stick to water. If you keep your fingers wet, I will not stick to you. I've also used spray silicone on a putty knife to scrape it away...

 

Yep, I've found that a lubricant is what i like to use. I'll have to try water,never thought of that.

 

I have gotten some Dynomat on my tools working on a friends car, I was able to just dunk em in CLR and then wipe off. So try to soak a rag in CLR and scrub.

 

M E K but use rubber gloves and a mask. spray on and scrape off with a putty knife..

 

Thanks fellas, I will give it a shot.

ive never tried on dynamat but on my o/t early 80's vw ive used dry ice to remove the factory sound deadner.

 

I used heat - not much, just enough to release it. I've never used it on dynamat but that oem soundener has to be removed for the 'stock' type race cars and i have removed a ton (literally) of that stuff.
It took a while to get the technique because it is easy to overheat. I would warm a large area and then use the torch and knife to start lifting and pulling it free. It would come out in sizeable pieces. A typical mustang has about 160lbs of it on the floors.

 

i have used mineral spirits.

 

Remove it with a Multimaster.



You can get the cheap one at Harbor Freight.

 

Try a heatgun-not to hot.

 

Only problem using heat is that I have read since its butyl based when it is heated up it becomes stickier? Not sure if this is true or not...... Thanks for all of y'alls input though, I will try all of them & report back.

Be careful of MEK. It can hurt you. Iinstead try 3M Adhesive Remover. Get it at your local automotive paint store. It comes in cans or spray. Spray around edges and let it work for a minute. It works well and does not harm paint.

 

oh forgot to mention when you do the dry ice one leave the block on the dynamat for a good 5-10 min then wack it with a dead blow and it should shatter and then you just gotta clean it up.

 

^^^^ seems like it would be easy but I think the button would clog the blade??

 

X2 on the dry ice.

 

WD-40 and a putty knife
