Alrighty, well when I did my sedan a couple of years back, I did the old hammer and chisel technique. what a pain in the arse. not too mention FREAKIN time consuming!
it looks like this (ps thanks for photo shanec86)
it breaks off in relatively small bits, and leaves a lot of work still to get rid of all the remaining deadener so you can paint over etc
so, only finding out about the dry ice method a couple of months back, I thought I'd give it a shot today on my new(er) car.
firstly, we have deadener at front and rear, and other little parts
I went down to BOC gases, and filled up the esky. it ended up being 11kg's worth of dry ice pellets - bout $60 all up.
when applying, gotta use gloves. so easy to burn yaself with dry ice.
spread the dry ice pellets evenly over all the deadener.
you will notice the dry ice starts to crack up parts of the deadener, as shown in this video - you can hear the deadener cracking up
best to leave it for a little while.
unfortunately i decided to crack open a beer while i waited, and as ya do, one beer lead to about 4 of them.
this was not good as it meant i had to really get stuck into it as the dry ice does have a limited life time before it vanishes (albeit a good 2 hours or so)
this shows the effect that the dry ice has on the deadener. just cracks up by itself in parts.
alright. time to get cracking. i just used a little scraper to pop up the pieces of deadener, which are very cold hard and brittle by now. what you will notice here is how it comes off in big pieces (not little ones like when you just use hammer, chisel and elbow grease)
this video shows that it becomes pretty easy to do -
was a bit of a struggle to sit on parts of the car even where there was no dry ice - the chassis was sooooo cold
look underneath the car and you'll see what i'm talking about
getting there
all done
just time to vaccuum now
then clean it up using a cleaning agent and it's ready to paint!
hope this is somewhat useful, even though it's all pretty straight forward and common sense.
using the dry ice method may cost you $60 or so, but it made my life a LOT easier compared to the last time when i did it all just with chisel and hammer. that took a solid day
this method took just over 2 hours from start to finish.
keep in mind these dry ice pellets are solidified co2, so it doesnt end up melting into a puddle of water in ur car, it simply evaporates (hope that is a correct, scientifically )
give your local boc outlet a call to arrange picking up some dry ice for the job - https://boc.com.au/boc_sp/au/contact_us/BOC...0Gear%20Centres
best of luck boys
