Got somebody you want to punish? Excellent! Have I got the answer for you. The next time you want to punish somebody and waterboarding seems a bit extreme, just go ask them to go remove some Dynamat or similar sound dampening material. Yep, think Exxon Valdez cleanup. God bless the next generation of restoration folks who have to deal with all the metal we're sticking this stuff to.
If you prepped your metal properly and you used a roller and stuck that Dynamat on there real good(so the stuff would actually work), then congratulations, somebody is now screwed if they have to remove it. I tried all the tricks and techniques(heat gun, rip it off quickly, various scrapers, holy water). If it's a big flat surface, it's not too bad, but removing it from something complicated like the package tray and bracing behind the rear seat was absolute hell(you can actually hear Satan laughing). I could only remove small strips at a time using a glass/razor scraper and a little bit of heat. Running a heat gun in front of the scraper as I was removing it did seem to help a little. After you go through that, then you're still left with a lot of rubber residue stuck on the metal and that's where the fun really starts. You then get to scrape as much of that off as you can and then use a solution like mineral spirits(odorless if you don't want to hallucinate) and a boat(yacht) load of towels. That's the real sh_t part right there. I wish I had discovered and could share some sort of magical process for getting it off, but unfortunately I didn't find one. It just flat out sucks. I'm not sure if Dynamat comes off any easier than the B-Quiet product that I used or some of the other products out there.
My sympathy and prayers goes out to anybody faced with removing this stuff from complicated surfaces.

It was in the interior of my car which was still mostly assembled so media blasting wasn't really an option, however I don't think media blasting would have any affect on a tar-like substance such as that. You'd probably just end up with a layer of tar with a nice sand and perforated foil inlay.

did you try media blasting???
I think Chris's finished car would have been reduced to bunch of tar-like-goo and little more if he had tried that until it was all gone. That stuff is the absolute worst. I think I used B-quiet, and it B-quite a pain in the ass to remove. I shared your plight when I decided to change my master cylinder and pedal setup to a floor mount one, which involved cutting the floor, which involved pulling up the carpet, which then involved removing the B-quiet stuff.I was armed with only a bondo scraper, and soon gave up. I think Dick at BOS ended up using a chisel to scrape it off, which he claims is the preferred method. I want to say someone mentioned freezing the stuff first.

It helps to remove that stuff in the freezing cold, SO I guess hauling the car out of SD would be your first step.
On the early 50's cars that have gallons of rubber under coating on the bottom we turn the car on it's top on the rotisserre and let the rubber soak in with diesel fuel. I wonder if doing the same with the dynamat might make your life easier. If you media blast under coating it just goo's up unless it's 20 degree. Either way it still sucks to do.
I bet diesel fuel and an scraper makes your life alot easier.

The problem with being able to "soak" something like Dynamat is that darn foil layer. The foil blocks anything from reaching the tar layer, so you'd still have to get that foil off so the chemical can reach the tar layer. If you're going to pull off the foil layer, you might as well get as much of the tar to come off while your scraping off the foil. I agree with you though, after the foil is removed, soaking the remaining tar for a while with a chemical like diesel might make it just wipe off with some towels, but even so it's still a filthy and towel/time-consuming mess. For vertical surfaces, soaking would be a bit challenging.
Extreme cold might help because it might cause the tar to stick together better or even become brittle instead of coming apart as you're pulling it off, but I actually found it more difficult to pull the B-Quiet material away from the metal when it was "San Diego" cold(55 degrees). Maybe 'freezing' would yield a different result than just cold. The B-Quiet stuff is really sticky which makes it work great but kills the removal process.
Maybe some TNT? Flamethrower? :fire:

Half-way through the process, I considered using that on myself.

What about ice packs or maybe if you could figure out a way use dry ice.
Or just call the super hero MR FREEZE.
Did you call Dynamat?

Being in the floor covering business for 35 years I understand your situation. At least it doesn't have asbestos and resides in a teachers home. :unibrow:
I haven't personally worked with Dynamat so I guessing based on flooring options. Your best chance may be dry ice in a container that transfers temp. the adhesive has a chance of shearing with a tool like a gasket scraper. Freeze spray for real tight areas.
Another option, similar to decal removal, is finding and optimum temp that the adhesive releases using a heat gun.
The elbow grease method with razor blade scrapers then soak what you can't get with the scraper with a citrus based adhesive remover.
First I'd call Dynamat and ask them for solutions, after all it is their fault!! :D

I'm not sure if the time you use sitting there trying to apply ice packs or dry ice to patches of this stuff would be any less than the time it might save you just removing the Dynamat at standard temperature. Probably a wash at best. Mr Freeze would have been perfect though. :lol: He could've also kept my beer cold.
I'm actually using a product called B-Quiet Ultimate. It's basically the same thing as Dynamat. Matt(69MSA) mentioned he uses the same thing. A while back I found an unbiased comparison of the 2 products which found that B-Quiet was just slightly lighter and stickier than Dynamat and worked just about the same. B-Quiet is a bit cheaper also. That was about 3 or 4 years ago. I think Dynamat removes slightly easier than B-Quiet, but is still a pain in the arse as well.

I know exactly what you mean. I had a new tunnel built in my Chevelle for the installation of the T56 Magnum and the guy had to hand scrap all that Dynamat tar stuff off of the old floor where he had cut out the old floor section so he could weld in the new metal. I was at the shop a couple of times and I felt sorry for the guy. That stuff took alot of muscle and gritting his teeth together. And that was just the outline of where he needed to weld in the new tunnel. I would hate to imagine someone having to scape a whole floor. I've included a pic of where you can see the outline weld of the tunnel. You can see where the rest of the Dynamat was left down.

How about one of those multi function tools that look likw a 4" grinder but scrape, cut, sand. I saw some at Harbor Freight pretty cheap. Maybe you can get under it with that and have someone pull it as you go. or even with the ice or dry ice.
Matt@BOS
02-01-2011, 03:02 PM
Chris, if I were you I would try using some dry ice. I don't think it is that hard to come by these days, and if you buy a whole bag, just put it in a tub with some beer for when you're done. Even if the dry ice doesn't work on the dynamat/B-quiet, the beer will be so cold that it will be worth the effort.

Yep, I found a slight amount of heat did help a little. It allowed my razor scraper to nearly get everything off at times(in 2 inch wide strips). Flat surfaces where you can get a good run going with the scraper and heat aren't too bad. It's the curves and beads and tight spots that are the time and towel consumers.
First I'd call Dynamat and ask them for solutions, after all it is their fault!! :D
Well, whether it's Dynamat or B-Quiet, the product is actually doing what it's supposed to when it's sticking to the metal like a muthaf#$@, so we can't really fault them. It would be cool though if they developed and released a "Best Possible Removal Kit/Process". As more and more cars get this stuff applied to them, future restoration folks are gonna need all the help they can get.
Be thankfull you are removing it from metal and not trying to save a plywood or particleboard subloor in a 15' x 20' room. Metal and concrete make it simple........kinda. :D

I'm actually done removing what I had to remove(there's still some stuck in my teeth though), but the tub full of beer and dry ice sounds like a fun new project. That one I don't mind asking help with. :thumbsup:

Someone is taking RTTC seriously----taking the Dynamat outta the car, removing the sub, adding an accusump---if it shows up with 200 treadwears on it, man--we got ourselves a serious playa---
So, what are you doing with that old sub enclosure buddy ole pal? :lol:
See you soon brother!

Its real easy to buy some bricks of dry ice. Just smack it into pieces... spread the pieces over .. for example... just the drivers side floor. Let it sit for a while.. then grab a air chisel. Or even just a hand chisel. It comes right up.
The dry ice trick works real well. I've done it with the entire floor of my car. Still take s some time.. but is not even close to the stressfulness of trying to melt it off. :thumbsup:

LOL! I figured my good old brother would chime in at some point and give me some hell. :lol: Dude, quit giving away all my secrets. I don't want anybody to understand how I went from 45th place to 44th in one year's time. It was all because of the 4lbs of sound deadener I removed, hell yah.
I'm removing the B-Quiet in spots because I was bored and decided to prep early for a roll bar and eventual mini-tubs to be installed some point in the year 2034. Also, the B-Quiet on the rear speaker shelf and rear seat supports simply was overkill. The sub and amps have been in and out several times since 1 month before last year's RTTC so that's nothing new, smartass. :) The Accusump was added because, as you all got to hear at last year's RTTC, my engine likes to spin rod bearings. Same 300 tires, although I may smear some B-Quiet tar all over the tires to make them stickier. :lol: Maybe I'll be a little faster because I can actually steer and stop this year. The big changes will come next year after I successfully pull off a bank heist. I need a driver so if you're up for it? I'll be fair on the split. :)
I'm keeping the sub enclosure and all the trunk panels and stuff. It swaps in and out fairly easily. Sometimes it's helpful for car shows where they actually give points for cute trunk setups(yawn).
It's funny you have time to give me hell about some sound deadener removal because your Apollo 13 thread is screaming out 'Update Me'. I guess you're in super stealth mode. I hope that hydro metal of yours is as straight as ever. :unibrow:
Can't wait for RTTC. Let's pray the weather holds. See you soon brother. :thumbsup:

I think I should have just stayed down in So Cal until the RTTC II event. I'm still not home from BJ Auction and GRNS!
EEEEEEEEEEHHHHHHHHHHHAAAAAAAAAAAAA
Dave -- I feel your pain! I've done what you're doing with the Dynamat... it's just LABOR. Although I like the dry ice freeze idea. Cold and brittle would be better than warm and gooey.
Can I put 200 treadwear on the S for the event? Maybe Mary P would beat you putting it in 43rd place! :rofl:
Chris,
I am sorry I can not contribute to finding another solution that hasnt been already mentioned......... but I do want to thank you for your comical choice in wording. I enjoyed reading your 1st post..... it made me laugh on this otherwise mundane day !
